Load balancing between two interfaces on 2811

Hi,
We have a 2811 router with VPN and NAT configured. We have two internet connection from different ISPs. The speed of our original connection is 2MB up and down. The speed of our new connection is 1MB up and down. We want to configure load balancing between the two connections. Our new ISP has provided us with a CISCO 837 router. We want to connect that router into our 2811 on one of the free WIC card and then configure load balancing between the two interfaces on our 2811. The third interface has a local address configured. Please suggest where to start. I tried searching on net for any configuration example but I was unable to find any particular example with commands. I am new on CISCO platform. Any help will be hugely appreciated. Thanks in advance.

Raju,
you have two choices as far as I can see. If you want to use static routing over the WAN to your branch, you could duplicate your static routes to the branch and point them to the secondary router. You will have two identical sets of static routes in the primary router, one set pointing to the WAN interface and the other one pointing to the secondary router.
ip route x.x.x.x "WAN-interface"
ip route x.x.x.x "secondary router"
ip route y.y.y.y "WAN-interface"
ip route y.y.y.y "secondary router"
etc.
As a result the primary router will have two routes to the branch and will load-balance. If one next-hop fails (either the WAN interface or the secondary router), only the other will be used. If the next-hop comes back up, load-balancing will resume.
The other choice would be to use EIGRP over the WAN, and make sure the two routers become EIGRP neighbors. Then you can use the "variance" command to achieve unequal cost load-balancing between the two routers. Let me know if you need more information about this, but i think static routes will be sufficient in your situation.

Load balancing between two routers

I have two routers connected through the LAN connection. The first one is using as routing protocol EIGRP, the other one is part of the managed service and I do not have access to it. I would like to make a load balancing between the two of them by redistributing the static routes in EIGRP. When I tried this, I am loosing the EIGRP entry for this route in the routing table. I would like to have both of them , so we could have traffic sharing. I appreciate if you give me any hints.

Load-Balancing between Foreign and two Anchors

Hi, we have two foreign controllers (one active, one standby) and two anchor controllers. All APs are connected to the active foreign controller. The layer 3 networks for the wlan clients on both anchors are different for the same SSID. SSID: Internet, anchor 1: Subnet A, anchor 2: Subnet B. So when a client is getting anchored to Anchor 1, the clients will get an ip from subnet A and when the client is getting anchored to anchor 2, the client will get an ip from subnet B.
This is so far not a big problem because we only have a few accesspoints in some rooms. But what will happen, when we have a full covered wlan and the client roams from one AP to the other AP? Is there a possibility, that the client will anchored to a different anchor while roaming? I think this will result in a lack of connectivity because without a real disconnect the client will not ask for a new IP address.
Other question: Is it possible to disable this load-balancing between anchor controllers? Or can i make a client sticky to only one anchor as long as an access-session is established?
All controllers are 5760 with 3.3.3 software.

Hi acontes,
It's an interesting question.
In this case, if all AP's are on WLC-A and there is no possibility that an L3 inter-subnet roam will occur between WLC-A and WLC-B, I would just forward WLC-A to Anchor A and WLC-B (in the event of fail over) to Anchor B (if Anchors reside on different subnets). If you must specify Anchor A and Anchor B on each WLC for redundancy purposes, it's important to understand the guidelines and limitations with regard to Foreign / Anchor Design.
As Scott mentioned, the limitation with Anchoring design is that there is no primary / secondary configuration for an Anchor on the Foreign WLC.
If WLC-A has two entries (1) for Anchor-A and (2) for Anchor-B, the EoIP tunnels are establish and load-balancing occurs in a round robin fashion.
Keep in mind the following with regard to guest N+1 redundancy:
•A given foreign controller load balances wireless client connections across the list of anchor controllers configured for the guest WLAN. There is currently no method to designate one anchor as primary with one or more secondary anchors.
•Wireless clients that are associated with an anchor WLC that becomes unreachable are re-associated with another anchor defined for the WLAN. When this happens, assuming web authentication is being used, the client is redirected to the web portal authentication page and required to re-submit their credentials.
Since traffic is transported at Layer 2 via EoIP, the first point at which DHCP services can be implemented is either locally on the anchor controller or the controller can relay client DHCP requests to an external server. Since the IP address directly correlates to the DMZ subnet or the interface where the traffic egresses, it is possible for some clients to get IP's from both Subnet A or Subnet B in the event that WLC-A is building EoIP to both anchors.
1) What happens if my clients roam?
Nothing... since all AP's are on WLC-A, it's Intra-Controller Roaming
Each controller supports same-controller client roaming across access points managed by the same controller. This roaming is transparent to the client as the session is sustained, and the client continues using the same DHCP-assigned or client-assigned IP address. The controller provides DHCP functionality with a relay function. Same-controller roaming is supported in single-controller deployments and in multiple-controller deployments.
Would it be better to choose the same DHCP Pool on both anchors?
It's probably better to have redundant anchors on the same subnet, but it's not required.
3) How would you design this :-)
WLC-A <--EoIP--> Anchor A (DHCP Pool A)
WLC-A <--EoIP--> Anchor B (DHCP Pool A)
It's important to remeber what Scott mentioned about the lack of a primary / secondary relationship. If multiple controllers are added as mobility anchors for a particular WLAN on a foreign controller, the foreign controller internally sorts the controller by their IP address. The controller with the lowest IP address is the first anchor. For example, a typical ordered list would be 172.16.7.25, and 172.16.7.28. If the first client associates to the foreign controller's anchored WLAN, the client database entry is sent to the first anchor controller in the list, the second client is sent to the second controller in the list, and so on, until the end of the anchor list is reached. The process is repeated starting with the first anchor controller.
If any of the anchor controller is detected to be down, all the clients anchored to the controller are deauthenticated, and the clients then go through the authentication/anchoring process again in a round-robin manner with the remaining controller in the anchor list. This functionality is also extended to regular mobility clients through mobility failover. This feature enables mobility group members to detect failed members and reroute clients.

Round robin DNS for load balancing between multiple network adapters (Xserve)

I'm attempting to use 'round robin' DNS to load balance between the two ethernet adapters of an Xserve.
Both ethernet adapters are connected to the same LAN and have static IP addresses of 192.168.2.250 and 192.168.2.251.
The DNS zone for the server's local domain/host (macserver.private) has a machine record with both IP addresses (set up in the Lion Server UI).
Having read up on round robin DNS, I would have expected DNS requests for 'macserver.private' to be answered with the two IP addresses ordered at random, achiving my aim of requests being served at random via each ethernet adapter.
However this doesn't seem to be the case. Doing a 'nslookup' from any of the network clients results in the two IP addresses being listed in the same order everytime. And pinging 'macserver.private' only ever results in a response from the same address.
Does anyone know why this is the case? Does Lion Server use a non-standard DNS configuration? Are there any additional settings I need to configure in Lion's DNS server to make adopt a round robin approach to responding to requests?
Thanks in advance for any help!

Be careful what you wish for
Round Robin DNS is rarely the best option for 'load balancing'. At the very least it's subject to caching at various point on the network - even at the client side, once the client looks up the address it will cache that response - this means that subsequent lookups may be served from the client's cache and not refer back to the server. Therfore any given client will always see the same address until the cache expires.
I suspect this is what you're seeing.
You can minimize this by setting a lower TTL on the records. This should result in the response being cached for a shorter period, meaning the client will make more requests to the server, with a higher change of using the 'other' address.
However, you're also going to run into issues with the server having two interfaces/addresses in the same LAN. This isn't recommended.
As Jonathon mentioned, you may be better off just bonding the two interfaces. This will provide an automatic level of dynamic load balancing without the latency of DNS caches, as well as automatic failover should one link fail (as opposed to round robin DNS which will cause 50% of requests to fail until the client cache expires and a new lookup is performed (and, even then, there's still a chance the client will try to use the failed link).

Question about load balancing between Portal and ABAP

Hi,
I have the problem whit load balancing between Portal and ECC (ERC) ABAP
Exist two system:
1) ECC (ERP) ABAP = Backend Module = HR
2) EP (JAVA) = Frontend
The users (9000 users) logon in the EP and run query (data personal) in the ECC. The problem to all user connect in Central Instance and not in the Dialog Instance.
How can balancing the conecction HTTP (EP) to ECC (ABAP)??
I need balancing in the ECC to Dialog Instance

Jco -> right. Another possibility is that you use iviews that point to the backend in this case you will need to use a load balanced entry for the backend system in the [system landscape|http://help.sap.com/saphelp_nw70ehp1/helpdata/en/47/8c1e438d7017fce10000000a42189c/frameset.htm] -> SAP_R3_LoadBalancing
If you have ESS deployed on your portal, you will most probably need to do both.

Distributed Queue - Unable To Load Balance Between Each Time A Send Method Is Called

Hi,
          According to the JMS documentation, I should be able to get the
          distributed queue to load balance
          between each time the message producer calls Message.send(). I was not
          able to achieve this, however,
          I noticed the load balancing happens when a JMS client is stopped and
          restarted (meaning totally
          exit the JVM and restart the JVM).
          Here is my configuration:
          WLS 8.1 SP2 on XP
          One cluster with two nodes (running on the same machine w/ different port)
          Each node hosts one JMS server, which hosts one physical queue and using
          JDBC store
          One distributed queue with two physical members from each of the JMS
          server.
          JMS Connection Factory is configured with "Load Balancing Enabled" set to
          yes,
          and "Server Affinity Enabled" to no. This connection factory is target to
          the cluster.
          The queue session for the queue sender is created with transaction setting
          to false.
          Any hints and ideas would greatly appreciated.

Thanks for the Makiey. I am surprise that BEA hasn't come back with any

Difference in GL Balances between two Standard Report fbl3n and fagll03

Hi ,
Mismatch of balances between two standard report ie.fbl3n and fagll03 . We are giving the complete example of what we are facing right now ... please go through the examples .
ENTRY NO. 1
We have posted one MIRO , Accounting Posting is as below : -
PK         Description    Amount
86         GR/IR             1000.00
31         Vendor           -800.00
50          TDS               -200.00
ENTRY NO. 2
We have Reversed the MIRO through MR8M , Accounting Posting was as below : -
PK         Description     Amount
21         Vendor             800.00
40          TDS                 200.00
96          GR/IR            -1000.00
But in Standard report FAGLL03 , .The line items of above twoi entries under GL " TDS " are showing in this way : -
Doc No.      PK      Ammount
Entry 1       50          -200.00
Entry 2       40          -200.00 -
> ?????
*OPEN ITEMS          - 400.00----
> ?????
Although in other Standard report FBL3N , the same are showing correctly as shown below
Doc No.      PK      Ammount
Entry 1       50          -200.00
Entry 2       40          +200.00
*OPEN ITEMS                0.00
PLEASE HELP
Regards
Soumitra Bhattacharya

Hi
FAGLL03 - Display/Change Items (New) - this report is related to ledger reporting purpose. this reports is available after ECC 5.0.
FBL3N - is line item display - this is only GL reports (not in ledger reporting)
if you find any difference is values please check the report variant you are using and ledger you are activated.
hope this will help you.

Load balancing between application server and database

Hi,
is there any load balancing between the application server and the database? Consider we have a single instance of an application server that sends database queries from different clients to the database. Are the requests queued in some way at the application server, allowing to control the flow of the queries (e.g. queries from "more important" clients might be sent with a higher priority)?
Thanks for your help!

Hi Victor/Jim/Volker,
Thanks a lot for all the responses..
Just wanted to let you guys know that my installation finished successfully.
The thing which confused me was that my Qtime, Qdate and everything else was showing correct values..
Well, my problem I set the environmental variable PASE_TZ to the EST time zone on a SYS level using WRKENVVAR>F4>SYS and added the variable. I logged off and the sidofr logged off, but one user which should have logged off and didn't was the "SAPINST"(my installation user) which was logged in the subsystem TMKSVR00.
Even when I had closed the SAPINST installlation program, the user doesn't log off...it just sits there until and unless u shut him out of the system using the option 4 on wrkactjob for ending the JOB(SAPINST logged in the system below the TMKSVR00 subsystem)
So since the SAPISNT user never logged of, his environmental variables were not initilized properly, even after the changes...
This thought came to me almost after a 6 hours of wasting my time searching for notes here and there...
I think when u end/stop the install in SAPINST, the SAPINST user should log off the AS400 system, but I have noticed, it never does...although when u restart the installation, if u have noticed it shows you the log on for the SAPINST user in the TMKSVR screen...
Its kind of buggy, I would say...
I have noticed, that even when I log on to AS400 from home or from a remote PC using Emulator, it shows me logged in the subsystem and even after i have logged of, it still shows me there...
Anyway, thanks a lot guys...for all your responses..
Just wanted to let you know all.
Thanks

Load balancing between Instance for same external IP client

Hi,
I have a azure website which is single tenant and is going to be used inside a single Domain from same region.
Now my website provide good performance till 20 concurrent request. I want to scale this so that it can reach up to 30 - 40 -100 so on.
What are the options available to achieve this. till now what i have figured out is that
1. If i increase the web site instance or on the auto scale option. It load balances between the instances on the basis of Client external I.P. but in my case all the users which are using the site shares the same external IP.
I have tested it increasing the instances doesn't make any impact on my performance results.
2. I have also looked in traffic manager but that case is valid when the clients are on different GeoLocations which is also not valid in my case.
So my basic Question is if i have a pool of different scenarios where
100 users uses 1 azure website
200 uses uses 1 azure website
1000 users uses 1 azure website
what infra should i take for each website to support this have performnace same as 100 users.

Hi,
I would request you to configure Web hosting plan and check if it helps in increasing the performance.
It gives a set of features and capacity that you can share across your websites separately.

NAT between two interfaces

Good day,
I would ask if it is possible to do NAT between two Interfaces on the same device?
The problem is that I need access from my inside lan to the management interface on the ASA. We will not manage the ASA over the inside interface.
This is my current NAT statement:
nat (inside,mgmt) source static 172.20.200.0-24 192.168.3.222 destination static 192.168.3.0-24 192.168.3.0-24 unidirectional
This is my PacketTracer output:
Phase: 1Type: ROUTE-LOOKUPSubtype: inputResult: ALLOWConfig:Additional Information:in 192.168.3.0 255.255.255.0 mgmt
Phase: 2Type: ACCESS-LISTSubtype: logResult: ALLOWConfig:access-group inside in interface insideaccess-list inside extended permit ip 172.20.200.0 255.255.255.0 anyAdditional Information:Phase: 3Type: IP-OPTIONSSubtype:Result: ALLOWConfig:Additional Information:Phase: 4Type: NATSubtype:Result: ALLOWConfig:nat (inside,mgmt) source static 172.20.200.0-24 192.168.3.222 destination static 192.168.3.0-24 192.168.3.0-24 unidirectionalAdditional Information:Static translate 172.20.200.1/0 to 192.168.3.222/0Phase: 5Type: USER-STATISTICSSubtype: user-statisticsResult: ALLOWConfig:Additional Information:Phase: 6Type: FLOW-CREATIONSubtype:Result: ALLOWConfig:Additional Information:New flow created with id 244039047, packet dispatched to next moduleResult:input-interface: insideinput-status: upinput-line-status: upoutput-interface: mgmtoutput-status: upoutput-line-status: upAction: allow
So NAT seems to be working correct. I can reach other devices behind the mgmt network this is no problem. But I cant access the ASA on the mgmt interface 192.168.3.2.
Clould it be a problem with the traffic flow? Because in the PacketTracer output I see on Phase1 a Route-Lookup and later on Phase4 the NAT statement.
Is there a way to get this working?
Many thanks for your feedback.
Brgds,
Markus

Hi,
To my understanding its not possible to connect to an ASA interface through interface other than the interface where the IP address is located.
In other words you are not able to connect from behind "inside" to the IP address of "mgmt" interface
I will try to find you a link to some Cisco documentation stating this. (I have never really had to find it though)

ACE30 load balancing across two slightly different rservers

Hi,
is there a possibility to get a load balancing across two rservers so:
when client sends http://vip/ and it goes to rserver1 then url is sent without change
when client sends http://vip/ and it goes to rserver2 then url is modified to http://vip/xyz/
Or maybe load balancing can be done across two serverfarms ?
thanks

Ryszard,
I hope you are doing great.
I do not think that´s possible since the ACE just load balance the traffic to the servers and once the load balance decision has been taken it will pass the "ball" to the chosen server.
Think about this, let´s say user A needs to go to Server1 but guess what? based on the load balance decision it was sent to Server2 which unfortunately does not have what the customer was looking for. OK, fine, user A close the connection and tries again but now the Server1 is down then the only available is Server2 then the ACE sends it to Server2 again then user A just decides to leave, you see how bad that can be.
A better approach would be to have either 2 VIPs ( different IP addresses) or 2 with the same IP address but hearing on another port, perhaps, one port per server.
Hope this helps!

ASA5510 - Verifying NAT is fully disabled between two interfaces

Hello,
I am trying to configure two inside interfaces without NAT. I am not using nat-control and I have added exemptions for the two networks. I can communicate between the two networks and to the Internet just fine.
I would like to verify that NAT is disabled between the two interfaces. I also need to make sure that the Interface IP (specifically for the traffic from inside-test to the inside network) is not added to packets between the two networks. I would like to be able to verify this as well. In other words I need to have the Source IP address from the originating connection on the inside-test network passed along through to the Inside network device without being replaced by the Interface's IP address. This is a test config for a production environment that will be using a load balancer. The config I have may be working in this regard and the load balancer may be replacing this IP address (that is what I am trying to test), but I am not certain.
So far I have the following NAT related running-config command (in regards to these two interfaces):
access-list NAT_Exempt extended permit ip 192.168.12.0 255.255.255.0 interface inside
access-list NAT_Exempt extended permit ip 192.168.3.0 255.255.255.0 interface Inside-test
access-list NAT_Exempt extended permit ip 192.168.12.0 255.255.255.0 192.168.3.0 255.255.255.0
access-list NAT_Exempt_2 extended permit ip 192.168.12.0 255.255.255.0 interface inside
access-list NAT_Exempt_2 extended permit ip 192.168.3.0 255.255.255.0 interface Inside-test
access-list NAT_Exempt_2 extended permit ip 192.168.3.0 255.255.255.0 192.168.12.0 255.255.255.0
nat (inside) 0 access-list NAT_Exempt_2
nat (inside) 1 0.0.0.0 0.0.0.0
nat (Inside-test) 0 access-list NAT_Exempt
nat (Inside-test) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface
global (Inside-test) 1 interface
Let me know if more information is needed for you to assist me futher.
Thank you.

Thank you Jennifer for your responses.
Do I need to include access-list commands for both directions for each interface as listed in my full config above, or do I just need one for one direction on one and one direction on the other interface (plus the exempt for the 69.x.x.x network)?
Would this config suffice?
access-list NAT_Exempt_2 permit ip 192.168.3.0 255.255.255.0 192.168.12.0 255.255.255.0
access-list NAT_Exempt_2 permit ip 192.168.3.0 255.255.255.0 69.87.157.192 255.255.255.224
access-list NAT_Exempt permit ip 192.168.12.0 255.255.255.0 192.168.3.0 255.255.255.0
access-list NAT_Exempt permit ip 192.168.12.0 255.255.255.0 69.87.157.192 255.255.255.224
nat (inside) 0 access-list NAT_Exempt_2
nat (inside-test) 0 access-list NAT_Exempt
Will I need to clear xlate to see the results of this or will this take affect immediately? I can't really do that during business hours, but should be able to after hours if I need to.
Can you clarify what the global commands do? I keep thinking that it adds the IP of the Interface to packets as they go through the interface and that I should use a different config for the Inside-test network.
I will try the xlate detail to verify and let you know what I find.
Thank you.

Load Balancing on two server nodes at the sender side...

Hi Experts,
I am sending a huge message (this message is being splitted into multiple messages depending on the load and zipped, this whole process of splitting and zipping is done by the scripts) zipped from sender side , when I am monitoring in message monitoring tool I found that all the load is on one server node and other server node is free as we have two server nodes , how to distribute the message equally between these two nodes.
The same Load balancing is working properly at the receiver end (load is getting distributed between two server nodes). Not sure why this is not the case at the sender side.
Please throw some light on this issue.
Thanks a lot for your kind help in advance.

file size can be handeled in client java proxy and the message is parsed in xi. this will not have much of performance issue. but yes when the smae is handeled by xi. and yes this scenario can be efficiently handeled from java client proxy
limit on the number of 'field-set' lines you can send to the ITS?
