Cisco Ace asymetric routing - DNS traffic

Hi,
I am wondering if Ace supports asymetric routing.
In my setup Ace is connected to router with two transit L3 interface. Interface on the router side belongs to different VRFs (e.g. VRF-A & VRF-B). Router is running MPLS in order to connect to internet-border gateway router then to internet.
Now issue is Ace got the default route with the next hop as the router's interface in VRF-A. However the server's subnet (SVI on Ace) is advertised on router in VRF-B.
So the outbound traffic(DNS query) from servers to internet takes the default route with next hop of router's int in VRF-A and inbound traffic (DNS response) comes back via MPLS using the VRF-B. That is because server's subnet is just advertised in VRF-B so remote internet broder-gateway will see the server's subnet with route-target applied to it in VRF-B.
When I enabled the reverse-path forwarding on the transit interface I could clearly see in the Ace logs that DNS response is getting dropped on the ace. I have evn removed the reverse-path forwarding(nothing in the logs - but DNS response from internet still cant reach the servers). I think logically its still asymetrical routing from Ace's point of view but not sure.
Please can anyone confirm the solution to this issue. I am thinking if I advertise server's subnet in VRF-A as well then it will be symterical routing but not 100% sure if it will fix it.
So just wondering if there are any other options advisable ?
Thanks

Is it not possible to have a host route added to the destination server ? This would allow the traffic to be routed back the same way it came and thus the connection work ?
Try adding a static route onto the destination server along the lines of ...
route add [source address of server] mask 255.255.255.255 [IP address of ACE interface]
This would cause the traffic to be routed between the two hosts via the ACE module which is good because the ACE is acting as a router between the two network segments.
That's just what I would do but I understand that it may not be the option you want.
Good luck

RV220W Router ignores DNS manual setting of host directs everything to router DNS

I have set the default DNS settings of my RV220W Cisco router to OpenDNS servers.
However, on selected hosts I would like to bypass OpenDNS.
For example, on a Windows 7 I am using Google DNS. I setup network configuration and tested it with "nslookup microsoft.com", it shows the DNS server as being "Server: google-public-dns-a.google.com" with IP address of 8.8.8.8.
But for some sites I get blocked by OpenDNS. Which suggests that the router is ignoring the host DNS preference.

Urgent!!! Cisco ACE and asymetric routing assistance needed

I am wondering if someone can give me pointers on the cisco ACE
and asymetric routes. I've attached the diagram:
-Cisco IOS IP address is 192.168.15.4/24 and 4.1.1.4/24
-Firewall External interface is 192.168.15.1/24,
-Firewall Internal interface is 192.168.192.1/24,
-F5_BigIP External interface is 192.168.192.4/24,
-F5_BigIP Internal interface is 192.168.196.1/24 and 192.168.197.1/24,
-host_y has IP addresses of 192.168.196.10/24 and 192.168.197.10/24,
-Checkpoint has static route for 192.168.196.0/24 and 192.168.197.0/24
pointing to the F5_BigIP,
-host_y is dual-home to both VLAN_A and VLAN_B with the default
gateway on host_y pointing to VLAN_A which is 192.168.196.1,
-host_x CAN ssh/telnet/http/https to both of host_y IP addresses
of 192.168.196.10 and 192.168.197.10.
In other words, from host_x, when I try to connect to host_y
via IP address of 192.168.197.10, the traffics will go through VLAN_B
but the return traffics will go through VLAN_A. Everything
is working perfectly for me so far.
Now customer just replaces the F5_BigIP with Cisco ACE. Now,
I could not get it to work with Asymetric route with Cisco ACE. In
other words, from host_x, I can no longer ssh or telnet to host_y
via IP address of 192.168.197.10.
Anyone knows how to get asymetric route to work on Cisco ACE?
Thanks in advance.

That won't work because ACE uses the vlan id to distinguish between flows.
So when the response comes back on a different vlan, ACE can't find the flow it belongs to and it drops it.
Even if we could force it to accept the packet, ACE would then try to create a new flow for this packet and it will collide with the flow already existing on the frontend.
You would need to force your host to respond on the same vlan the traffic came in.
This could be done with client nat on ACE using different nat pool.

Maximum cos1 (voice traffic) supported by Cisco ASR 1006 router

Dear Team,
Please confirm the maximum cos 1 traffic supported by cisco ASR 1006 router.

Yes, it would. If you are planning on terminating a single site on this router I would spread over multiple routers for redundancy.
Table 6 explains number of ports and channels providing you have the DSPs:

Need help to Configure Cisco ACE 4710 Cluster Deployment

Dear Experts,
I'm newbie for Cisco ACE 4710, and still I'm in learning stage. Meanwhile I got chance at my work place to deploy a Cisco ACE 4710 cluster which should load balance the traffic between two Application Servers based on HTTP and HTTPS traffic. So I was looking for good deployment guide in Cisco SBA knowledge base then finall found this guide.
http://www.cisco.com/en/US/docs/solutions/SBA/February2013/Cisco_SBA_DC_AdvancedServer-LoadBalancingDeploymentGuide-Feb2013.pdf
This guide totally fine with my required deployment model. I have same deployment environment as this guide contains with ACE cluster that connects to two Cisco 3750X (Stack) switches. But I have some confusion places in this guide
This guide follow the "One-armed mode" as a deployment method. But when I go through it further I have noticed that they have configured server VLAN as a 10.4.49.0/24 (all servers reside in it) and Client side VIP also in same VLAN which is 10.4.49.100/24 (even NAT pool also).
My confusion is, as I have learned about Cisco ACE 4710 one-armed mode deployment method, it should has two VLAN segments, one for Client side which client request come and hit the VIP and then second one for Server side. which means besically two VLANs. So please be kind enough to go through above document then tell me where is wrong, what shoud I need to do for the best. Please this is an urgent, so need your help quickly.
Thanks....!

Dear Kanwal,
I need quick help for you. Following are the Application LB requirements which I received from my clinet side.
Following detail required for configuring Oracle EBS Apps tier on HA:
LBR IP and Name required to configure EBS APPS Tier (i.e, ap1ebs & ap2ebs nodes)
Suggested IP and Name for LBR:
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm detail for LBR Setup
Following detail will be use for configuring the LBR:
LBR IP and Name :
IP : 172.25.45.x [should be on same 172.25.45 subnet of ap1ebs & ap2ebs nodes]
ebiz.xxxx.lk [on port 80 for http protocol accessibility]
This LBR IP & name must be resolve and respond on DNS network
Server Farm Detail for LBR setup:
Server 1 (EBS App1 Node, ap1ebs):
IP : 172.25.45.19
Server Name: ap1ebs.xxxx.lk [ap1ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Server 2 (EBS App2 Node, ap2ebs):
IP : 172.25.45.20
Server Name: ap2ebs.xxxx.lk [ap2ebs hostname is an example, actual hostname will be use]
Protocol: http
Port: 8000
Since my client needs to access URL ebiz.xxxx.lk which should be resolved by IP 172.25.45.21 (virtual IP) via http (80) before they deploy the app on the two servers I just ran web service on both servers (Linux) and was trying to access http://172.25.45.21 it was working fine and gave me index.html page. Now after my client has deployed the application then when he tries to access the page http://172.25.45.21 he cannot see his main login page. But still my testing web servers are there on both servers when I type http://172.25.45.21 it will get index.html page, but not my client web login page. What can I do for this ?

Cisco ACE loadbalancing matching more than one header in L7 class map

Dear All,
This is regarding Cisco ACE loadbalancing matching more than one header in L7 class map. I have a small setup with ACE 30 module in Cisco6500. I have got three webservers. Presently I have following configuration where I am mathing one url header.
class-map type http loadbalance match-all L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
So for above configuration, when traffic is coming for abhisar.com, it is working fine.
Now, I have following headers and DNS entry is pointing to same virtual IP for all http url header same as abhisar.com
abhisarindia.com
indiaabhi.com
So new configuration will be
class-map type http loadbalance match-any L7_WEB_HEADER_MATCH
description MATCH THE HOST HEADER OF HTTP REQUEST
2 match http header Host header-value ".*abhisar.com*"
4 match http header Host header-value ".*abhisarindia.com*"
6 match http header Host header-value ".*indiaabhi.com*"
So just want to confirm if this is fine.
Thank You,
Abhisar.

Dear Rajesh,
Thank you for reply. I will let you know once I carry out this activity.
Thank You,
Abhisar.

ACE in routed mode

My first question, can anyone recommend some very heavy reading discussing the ACE modules and associated traffic flows and order of operations? Not just how-to scenarios.
And the primary question that brings me here:
I've got an ACE module in a 6500 chassis that's configured for routed mode. For the purpose of this question we'll say that on the ACE I have a single VLAN for vIPs and a single VLAN for rservers. vIP VLAN is 12 and rserver VLAN is 101. I have a pair of App servers being load balanced, and a pair of Web servers being load balanced.
When user devices send traffic to the Web servers vIP, traffic hits the SVI for VLAN 12 and the service-policy is applied manipulating that traffic and sending it to the VLAN 101 SVI and on down to an rserver. The same if user devices are sending traffic to the App servers vIP.
When a Web server tries to send over to the App servers vIP, I get no response. In fact, from the Web server I can't even ping my gateway (SVI for VLAN 101). How do I get the Web server to send traffic loadbalanced across the App servers?
Here's an example ACE config:
access-list ALL line 8 extended permit ip any any

Hi Adam,
You can check Gilles' DC t-shooting guides that should give you a very good overwiew about packet processing on the ACE; also you can check
the Cisco wiki site where you find the scenarios plus a detailed explanation for traffic management.
Now going back to your issue, you problem can be splitted in two parts.
1. Web server not able to ping VLAN 101 ACE's SVI.
ACE is a closed device, meaning that access to each Interface/VLAN needs to be explicitly configured; you need to apply the management policy
to the 101 SVI to allow ICMP or any other management protocol. You can apply the same (service-policy input MGMT-ACCESS) or create a new
one just for ICMP, that's up to you.
2. Web servers not able to communicate with APP servers thorugh VIP.(vise-versa)
Problem here is that servers are trying to communicate through SVI 101 but no VIPs are applied to it so the ACE will simply discard the packets
for 10.10.12.20/10.10.12.21 on that interface, servers have the ARP and everything to reach those VIPs but the ACE has not been instructed to do
load balancing for clients reaching it out through VLAN 101.
In order to do load balancing between APP & Web Servers you need to configure L4-CONTEXT-A-VLAN on SVI 101 as well.
Also since your servers are sitting all in the same VLAN you're going to need client NAT to prevent assymetric routing on server-to-server communications.
I've attached a sample with NAT based on your config.

Slow connection in one server if accessing through Cisco ACE

Hi,
Good day, Can someone help me on my problem? I have 3 servers, server1, server2 and server3. When one pc accessing the server 3 application via Cisco ACE, it experienced a slow connection but when direct access without Cisco Ace, it's fast. The connection of this PC through cisco ace and direct access have no issue.

Hi Earsdale,
All the three servers are using the same configuration, so, I'm afraid it's not possible to give you a simple answer. You will need more troubleshooting.
I would recommend you to start by checking the differences between the servers because one of those differences is certainly causing the failure.
Also, it would be helpful to get traffic captures on the TenGig interface of the ACE to compare the behavior of the connection when going to the different servers, as well as the differences when being load-balanced vs accessing the server directly.
If you need help with this troubleshooting, you can always open a TAC service request

Cisco ACE dynamic rerouting (dc to dc failover)

Good day,
We currtenly have two dc's (site A and site B)
We are using netapps as our SAN and we ar booting our server directly from the SAN
SAN A and SAN B are insync and the network between site A and site B is routed.
The challange:
When a server is failover from site A to B it still has an ip adress that is routed to site A.(due to the SAN boot)
We have a cold - hot design in regards to the servers (so no clustering of ESX)
I have been reading about cisoc ACE and i think that it would solve the challange by dynamily updateing OSPF.
Can any one please confirm that cisco ACE will solve this challlange (whitout the need for any other additional hardware)
Thanks a lot,
Regards,

It's more related to disaster recovery planning than ACE configuration
The cleanest way is to use L2 extension.
Otherwise you can use VMWare SRM to change the ip addresses of your VMs, or run an OSPF process and replicate all the subnets and put it in the "shutdown state" (or announcing it with a very high cost, proximity routing will do the rest - ACE module can do this for the VIPs with OSPF route health injection, ACE4710 doesn't support RHI but on the upstream router you can define an IP SLA probe and perform conditionnal redistribution), or use a dummy VRF with all your subnets and when enabling DRP, perform route leaking... use NAT with DNS-based failover etc...
There is no generic answer to your problem.

Cisco ACE - "show conn" command queries

Hi all,
i have some queries regarding the "show conn" command in Cisco ACE.
Working Scenario:
VIP : 10.10.10.1
Server 1 : 10.10.20.1
Server 2 : 10.10.20.2
Client: 30.30.30.1
When a client 30.30.30.1 initiates a connection to the VIP on 10.10.10.1, the ACE load balances it to Server 1, 10.10.20.1. Looking at the "show conn" table, it shows that Server 1 is replying back to the Client 30.30.30.1 through the ACE.
Now, my question is when the ACE returns the traffic to the Client, should the Client be seeing the source IP coming from the VIP or Server 1? My understanding is that the Client should be seeing traffic returning from the VIP. But the show conn table does not seem to suggest so.
show conn table
conn-id    np dir proto vlan source                destination           state
----------+--+---+-----+----+---------------------+---------------------+------+
1768       1 in TCP   10   30.30.30.1:9221   10.10.10.1:80       ESTAB
41         1 out TCP   52    10.10.20.1:80    30.30.30.1:9221   CLOSED

Daniel,
The client is expecting a response from the VIP otherwise there would be an asymmetrical routing problem and conns will never complete.
The fact that you're seeing 30.30.30.1 as the destination address is just that the server is able to see client's IP address on the request, when your backend servers sends the reply back to the client this response is forced to go through the ACE, when the ACE looks at the packet it matches with a previously conn created on the flow table so it "NATs" the reply so now the source of the packet is the VIP and destination is 30.30.30.1.
This is a expected behavior as you're not using S-NAT on your network.
HTH.

Allow DNS Traffic

Hi!
We need to allow DNS Traffic from Lan to Wan network for our internal LAN Users through Cisco Router. May we have the lines to add in the router and do we need anything else to apply this access-list?
Thanks.

access-list 101 extended permit tcp net_lan sub net_wan sub eq 53
access-list 101 extended permit udp net_lan sub net_wan sub eq 53
access-list 101 extended deny any any
interface Serial 0/0
ip access-group 101 out
N.B. That access-list is only for permit traffic for DNS protocol. All traffic except DNS will be deny

Cisco ACE Module with Bluecoat Cache Proxy, Transparent and spoofing client IP

Hello Dears,
I'm trying to implement Cache loadbalancing through Cisco ACE Module.
I have 2 Bluecoat cache proxies, when i do configure transparent proxy without spoofing client IP, everything work properly, but when I enable spoofing client IP (reflect client IP address), clients are not able to access internet, although they are going to cache servers, I can see their sessions.
I'm afraid that I have a problem in the returned traffic PBR.
can anyone help please.
Thanks

Hi Ibrahim
I ahve reviewed the config. The ACE config is all god but I do see some issue with the switch side. If you are doing ip spoofing, then "match ip address" in pbr should be the client ip address. However, what you did is ip address between the ACE and MSFC. Try to configure the test client ip address into the below access-list.
msfc---vlan 265---ACE--vlan 264----CE farm
interface vlan 265

Cisco ACE compatiblity with F5 GTM

Hi,
We have cisco ace 30 modules installed in cisco 6500 switches. For application availability purpose from the internet, we need to have some global site selector/3rd party devices with similar feature set that of cisco gss.
My question is: whether cisco ace is compatible to ge tintegrated with other 3rd party devices like F5 GTM?
kindly sugegst..

Good afternoon,
I'm not familiar with the GTM solution, but, as long as it's DNS-based like the GSS, it should be perfectly compatible. Bear in mind that the ACE is not aware on how clients are getting the IP address, it just replies to whatever connections it gets.

Cisco ACE Inspecting RTSP Wowza Service?

Did somebody knows if Cisco ACE in some of their HW and SW versions support Inspect for RTSP of Wowza Service running in the serverfarm? We intend to setup the service in routing mode and without a Firewall or a Web APP Firewall avoiding BW consumption in ASA/FWSM.

Hi Samuel,
ACE does support RTSP inspection but specific server support is not mentioned. Please see more details about RTSP inspection at below:

ASA5525-X and Cisco 3850 Traffiic routing

Hi,
I apologise if this question has been answered already, I tried searching but found nothing.
I have a Cisco 3850X and an ASA5525 firewall, and I want to create a specific route from a particular VLAN in order to filter the traffic.
I am using VLAN 15, which is intended for wireless access only.
I want to;
Route all wireless hosts traffic on VLAN 15 to the firewall for filtering through two physical interfaces grouped together in a channel-group
Route filtered traffic back from the firewall into the same switch via the same channel-group (same physical interfaces.)
Allow filtered traffic to communicate with other VLANs via their gateways
If somebody could point me in the right direction with this I would appreciate it. I have attached a drawing of the physical cabling to give you a better idea of how the equipment is connected.
Thank you.

Hi Collin,
Thanks, I've now managed to create the trunk following your instructions.
I have set the switch up so that the trunks native vlan is 15, but vlans 10-15 are allowed. As follows:
Switch:
interface GigabitEthernet1/0/1
switchport access vlan 15
switchport trunk native vlan 10
switchport trunk allowed vlan 10-15
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-group 2 mode active
interface GigabitEthernet1/0/2
switchport access vlan 15
switchport trunk native vlan 10
switchport trunk allowed vlan 10-15
switchport mode trunk
switchport nonegotiate
speed 1000
duplex full
channel-group 2 mode active
Firewall
interface Port-channel10.10
vlan 10
nameif inside
security-level 100
ip address 10.196.10.1 255.255.255.0
interface Port-channel10.15
vlan 15
nameif dmz
security-level 50
ip address 10.196.15.1 255.255.255.0
same-security-traffic permit inter-interface
same-security-traffic permit intra-interface
I am able to ping the .15 gateway from a host sitting on VLAN15 on the switch, however, even with the 'same-security' configuration I am still unable to ping across to the .10 gateway.
I tried creating a route, 'route inside 10.196.15.0 255.255.255.0 10.196.10.0' however was returned an error message 'Cannot add route connected route exists'. However when I looked at sh route, no such route exists:
C 10.196.15.0 255.255.255.0 is directly connected, dmz
C 10.196.10.0 255.255.255.0 is directly connected, inside
C 192.168.1.0 255.255.255.0 is directly connected, management
I should not that I have only used the gateway addresses 10.196.10.1 and 10.196.15.1 in the firewalls configuration, I have removed these gateway addresses from the switch, as I assumed the firewall should be used as the gateway, and didn't want the switch to route between the vlans internally bypassing the firewall.
I'm obviously still missing something, might I have to setup NAT to translate the two addresses?
Thanks again for your help
