Can a hosts be in the same subnet yet not be link local (trouble with Bonjour) ?

I'm trying to print through a D-Link DVA G3810 BN from the wireless side with a Macbook Pro to the wired side HP C6280 . Apparently mDNS (Bonjour} communicates with hosts that are link-local and on the same subnet ? Is there an assumption that hosts on the same subnet are link-local ? My testing suggests to me that connections from the wireless to the wired side of the D-Link are routed and the hosts are NOT link-local . It will only allow me to add hosts , regardless of being fixed or via DHCP , within the same address range and subnet . I found a statement that for hosts to be link-local , their communications cannot be routed (pass thru a router) . I can't see the HP printer in trying to set it up and always get the 'Network host is busy ; will retry in X seconds' state if I do configure it as an IP type . I can't figureout a way around this issue with the hardware that I have to work with .

Link-local addresses are usually the self assigned IP address that a device will set when a DHCP server cannot be found. These are the addresses with 169.254.x.x subnet.
If the router is assigning IP addresses for your network, then they will usually have a different IP subnet, possibly 192.168.0 for D-Link. And this subnet would be for the wired and wireless connections. So it would be more a case of bridging the two network topolgies rather than routing them.
The network host is busy message could be more to do with the driver and the IP protocol selected when creating the queue than the connection being broken between the Mac and printer. If you were to open Network Utility and select the Ping tab, enter the IP address of the HP and set the pings to 4, pressing the Ping button will soon show if there is a path through the wireless to the printer.
If you get a response to the ping you could then open Safari and type the ip address as the URL. This would then connect to the internal web page of the printer and possibly let you enable an IP protocol like LPR so that you can use LPD on the Mac instead of Bonjour to connect to the printer.
As for the driver, you could look at using a Gutenprint driver instead of the HP driver or the hpijs package to get past the limitations that some printer drivers have with network connections.

How to know (cmdlet) If my Distributed Cache hosts belong to the same Cluster or not ?

Forum,
Our Farm has two servers that are hosting and running the Distributed Cache service. How can I know if both servers/hosts belong to the exact same Cluster? What is the command for that?

hi,
you can take help of the below articles it has list of powershell command to provide details of each host inside cluster

Can 2 vlans have the same subnet?

I hope the combined genius of the fellow community can answer me this. I am new to Cisco, and I understand VLANs as a physical boundary separating broadcast domains.
I was wondering if it is possible to divide 1 subnet (192.168.1.0) into two separate VLANS? I have all layer 3 switches in my environment. Making matters worse, there would be no pattern for the IP address assignments into VLAN-A vs. VLAN-B..
If this is possible, can you please explain the mechanisms for a successful implementation.

It mostly depends if/how you want hosts on them to talk one another (or other networks).
If the answer is "not at all" then you can have as many VLANs as you like using the same subnet.
If the answer is "completely" then you have to either a. break your addressing (L3) down to have one set of hosts in subnet A (on vlan a) and the others in subnet b (on VLAN b). or b. have some fancy tricks in place with network address translation (NAT) in place.
I'll leave the latter solution off as beyond the scope of your question.
For the former, you would just change your subnet mask - for example, if the classful subnet is a "standard" /24 (255.255.255.0) then split it in two - /25 or 255.255.255.128. Assign hosts in one or the other.
You have to have some pattern - all networking is based on patterns in some way or another.

Can VIP and Rservers be in the same subnet in ACE Routed Mode

Good Day,
Sorry for the lengthy post.
Currently I have a 6509s running in VSS mode with ACE30 in each chassis.
I have 5 vlans, which the VSS is the L3 interface for each. 1 Vlan is for management, the others are the data vlans for the servers.
The ACE is configured in bridge mode, with all VLANs going to a specific context (non Admin).
Some of the Host on each VLANs are not utilized for load-balancing. The default gateway for each VLAN is configured on the VSS.
I would like to setup the ACE in the routed mode, without having to change the IP address of each servers on different VLANs.
Basically I want to turn off the SVIs on VSS and move the L3 interface on the ACE Context, and let it perform the local routing for all the hosts.
I was going to add a new /30 L3 interface between the VSS and ACE to be utilized for default route traffic coming from the ACE Context, and static routes from VSS to ACE for traffic destined to host that are being load-balanced and not being load-balanced. Basically force the traffic through the load-balancer in/out.
For future deployment, I was planning on using different IP address for the VIPs, and Real servers (most likely RFC 1918).
From most of the examples I have seen the VIP and Rservers are in different Subnets. But because I am trying to not change the IP address of the rservers and VIP, I wanted to know if the VIP and Rservers can be configured to be in the same subnet where the ACE is in routed mode.
Unfortunately I don't have a spare ACE to test scenario.
As always any help would greatly be appreciated.

Raman

No ping between host in the same subnet

Hello,
I have a question about the ASA and the ARP traffic in IOS 9.1.2 for ASA 5585-X and multicontext. I have discovered a curious behaviour about the traffic ARP in the my CLUSTER of ASA's. When I try to send a ping between host in the same subnet and these host have as Gateway the interface of the ASA (ASA is his router) don't works, if I mark the check to enable the comunications between host connected to the same interface this cotinues without work. The only way to get my aim (ping between host), I need to implement and Access Rule allowing the traffic IP between my origin network and destination the same network.
I think that this is some feature of ASA that filter the ARP Request but I don't understand!!! Can I help me, please?
Thanks.

Hi,
Your firewall should not see any traffic between the hosts on the same subnet.
If it is seeing traffic between the hosts then its likely that Proxy ARP on the ASA is the problem. Proxy ARP is enabled on the ASA by default on all interfaces. This essentially means that when the host connecting to the other host on the same subnet sends an ARP request the ASA might reply to that ARP request instead of the actual destination host. This is why traffic might get forwarded to the ASA instead of the actual host.
If you want to disable the Proxy ARP on some ASA interface then you can use
sysopt norpoxyarp
Where you replace the with the actual name you have given to the interface on the ASA. This disables the Proxy ARP

I have read the doco by Ivan Kovacevic amongst many others but as my clients and servers are on the same subnet, the config doesnt work.
Can anybody point me in the right direction please. The devices are ACE 4710 running A3(2.3).
Thanks

Try using the following configuration:
Note: Please make sure to configure also a udp probe to probe udp port 69, in case the application is down.
You need to configure a management policy on the interface when using a UDP probe.
That is because, when port 69 on the server will be unreachable, the server will send an ICMP unreachable.
ACE will consider a udp probe as "failed" only when it sees ICMP unreachable.
Without a management policy-map, the ICMP unreachable message will be dropped.
Also, add an ICMP probe to the rserver because udp probe will not be enough when the physical interface will be down.
That is because UDP is a connection-less protocol. To consider a UDP probe successfull, ACE need to see NO answer from the server in respose to the probe.
The ACE will not see any answer from the server when the interface is down and thus, will consider the probe as "sucessful".
With ICMP probe attached to the rserver, you also test the reachability of the server and not only the UDP port.
Here is the configuration (of course, you can chage the names of the of the objects to the name you are using if you want) :
access-list ALL line 10 extended permit ip any any

Multiple Clusters on the same subnet

Hi,
We have two separate projects using coherence (3.5.2) in our location.
Unfortunately they will be deployed on the same subnet.
We use ExtencdTCP on the client side to connect to the cluster.
What steps should be taken so that Project1 (P1) is kept separate from P2...
We only have control over P1 or is there something that can be done purely from P1 config that will achieve this aim?
The config for the client is given below, since we can restrict the hostnames and the ports in the tcp-initiator elements, we can easily force the client to connect only to the relevant P1 machines.

Was able to override the multicast address thru the command line and have just P1 work with

Hello gdufour,
Actually i've got this configuration:
1.) One serverfarm (farm1).
2.) In this serverfarm, i have two real servers des1 and des2.
3.) The real servers are using VIP 10.24.16.10.
4.) The loadbalance is roundrobin using http with headers.
I want to have:
1.) One new server (a.b.c.d), it can be in the same subnett.
2.) This server don't know if can belong to serverfarm farm1.
2.) When i reach to http://index/url/url1, this has to be to VIP 10.24.16.10.
3.) When i reach the link, the VIP 10.24.16.10 redirect to server a.b.c.d.
4.) When the server a.b.c.d down, the serverfarm farm1 have to take the load of the url.
Is posible this configuration?
Thank you.
Best Regards

Is it possible to create two multicast DR on the same subnet?

on server vlan 10.24.254.0/24, there are two routers:
R1 is .2 and R2 is .3 with "IP pim sparse-mode" enabled.
R1 and R2 are on two distinct Mcast domains
R1 has
ip pim rp-address 10.25.249.1 acl-one override
R2 has
ip pim rp-address 192.168.2.1 acl-two override
The problem is R2 with higher IP address is now the IGMP and PIM DR. Any multicast app with RP 10.25.249.1 is NOT working because R1 can't receive IGMP join from servers.
In addition, R1 by design can not reach 192.168.2.1 and same for R2 to reach 10.25.249.1
Thus configuring two "IP PIM rp-address" is not possible
how can I make R1 the DR for group IP under acl-one and R2 for group IP acl-two?
or I have to change network topology?

There can be only one DR on a the same subnet.If there are more than one DR on the same subnet it would endup sending duplicate multicast traffic for connected host.For more information refer the URL

Multiple SSID's on the same subnet?

Can you have Multiple SSID's on the same subnet?
SSID1 authenticates clients via radius.
Our corporation bought printers with wireless cards that only support WPA-PSK so we created SSID2 for the printers. We can connect to both SSID's and ping from SSID1 to SSID2 but we can not perform other functions such as view the printer management interface with a browser. Should it be possibe to communicate between SSID1 and SSID2 on the same subnet?

Yes you should have no issue, but the only thing is that you are using a lower security method... so either you put them on different subnets so you can control the traffic via acl's or might as well use the same security method to make it easier. The fact that you can ping sounds like you should be able to http to the device.

Multiple Scopes for the same subnet with Cisco CNR

I have a requeriment from my internal client that he wants to have multiple scopes within the same /21 subnet , but he wants to have different scopes for each group of servers ( in the /21 subnet).
We have 2 Cisco CNR ( I dont know the version they are running because they are managed by an external vendor) but they are in active / standby mode.
My question is .. it is posible to make the CNR have different scopes (ranges of IP's) for the same subnet ( /21) and assign those based on the client ( I dont know what criteria can be followed .. maybe Mac Address ???).
I appreciate any help or pointing to the right documentation
Thank you in advanced

I don't know that you would want a separate PO print. You can print the same PO print twice to provide a copy for the freight vendor. I think it should be okay as long as it is clear that the PO is with the vendor for the products but there is a condition specifying the freight deal. The second vendor (say the freight vendor) should be okay with this PO as well. I don't remember how the standard SAP PO forms handled the vendor condition but it should be enough I would think. I never came across a separate PO for freight since it is usually an value added service that is an integrated part of shipping goods and the paper-work usually is leveraged from PO, bill-of-lading, etc. SAP will make it difficult if you do need a separate PO since there is no way to use account assignment to material and therefore would need to manually account code and invoice verification, post to a clearing account in FI for re-class to material or charge to internal order with settlement to material or something like this.
I would just make sure that the PO print makes sense in terms of being able to see the freight charge and maybe the vendor name or something (look at the standard SAP PO form to see what the best practice is).

be accessed from one port while another through a second port. Forexample,
we
have a application to be exposed through the firewall at port 7001.
Then we have
another admin application to only be accessed within the firewall. But
they need
to be deployed within the same JVM since they may have shared statebetween
them.
Thanks,

That's not true. WebLogic supports a non-secure and secure listenerport
at the
same time. That was one of the selling points for my organization.

Multiple 11gR2 Clusterware installations on the same subnet using GNS

Hi,
I am hoping someone could shed some light on an issue I appear to have regarding the installation of 11gR2 Clusterware.   The main issue is that I have a host-vip.subdomain that fails to startup on installation. This is my 3rd cluster in my environment; the other 2 installed/configured ..fine.   This install fails because the host-vip.subdomain does not resolve with its own GNS service.
Further investigation lead me down a path involving my other clusters.   I found in my DNS server /var/log/messages file that the host-vip.subdomain was trying to resolve to host-vip.subdmain.subdomain_clust1 on IP xx.xxx.130.20.   However, this cluster's GNS service is listening on xx.xxx.130.22
More detail on the environment:
I currently have in production, two 2-node clusters.   Not RAC..just 2-node linux clusters; On the production clusters, I do have a single-instance database running in a 'warm failover' configuration.   I do use SCAN to access each of the database on their respective clusters.
I am using GNS and DHCP (obviously) to generate the VIPs for each cluster.    Cluster1 GNS IP - xx.xxx.130.20 ; Cluster2 GNS IP xx.xxx.130.21.   Both are configured in DNS and resolve the SCAN address to each of the VIPs on that server.
When testing SCAN access to the database, I noticed that a tnsping DB1 - which uses SCAN-name1.subdomain1 connects fine.   Also, tnsping to DB2 using SCAN-name2.subdomain2 connects fine as well.
However, the weird part is that if I use each others subdomain..they still connect ...ie....tnsping DB1 using SCAN-name1.subdomain2 ...still connects to DB1.. albeit , it takes about 10x longer to get a response.
This has lead me to the idea that since GNS is basically a mDNS service, broadcasting on the subnet .130...could it be possible that ANY GNS service on that subnet could resolve a name lookup request for any other GNS on the same subnet , and during installation of a new server, cause a new VIP to go to the wrong GNS service ?
So, my question is this : Is there any requirement I may have missed that state multiple Clusters using GNS / SCAN MUST BE on different subnets, as to not interfere with each other's lookup requests ?
Any info would be helpful

Was able to override the multicast address thru the command line and have just P1 work with
the following overrides.
-Dtangosol.coherence.clusteraddress=P1Cluster -Dtangosol.coherence.clusterport=11111
where p1Cluster=224.2.1.99 (say)

Two WLC over the same SUBNET - selection from AP for determinate WLC

Hi
I have the next problem, my company have two WLC (WISM1 - IOS 7.0 and WLC2504 - IOS 7.4), and we have 4 types of APs (1131, 1242, 1040 and 1600), well the WISM 1 manages the old APs 1131, 1040 and 1242, the 2504 manages the 1600, this because the WISM 1 don't support the 1600
Well my question its how i can assigned to APs 1131, 1242 and 1040 to connect to WISM1 and not to 2504 , both are on the same subnet and the Ip its send for DHCP with option 43, others for DNS and apparently some of my APs connected to the 2504, I wish only connect to WISM 1
How i can set priority in the AP for conect to WISM1?, i read the High Availability on the AP, this is enough or should we make any extra settings the WLC
Thanks for the response
Regards

Hi Kashif,
I don't think you understand the nature of this thread. It is IMPOSSIBLE to configure a 2504 & a WiSM-1 for HA (AP SSO).

SRP521W - Local and Remote Traffic Cannot be the Same Subnet Address

I support an existing VPN infrastructure with PIX, Juniper NS5GT, and Netopia devices used as VPN endpoints. In all cases, I can create a VPN where the location's internal subnet, 10.x.y.0/24 sends traffic to 10.0.0.0/8 out the VPN tunnel. In the case of this 521W that we are evaluating, it appears that I cannot do this. Insteadm when creating the IPSEC policy I get this error "Local and Remote Traffic Cannot be the Same Subnet Address." Which, while strictly true, has never been an issue with all the above devices. Is there a workaround or other methodology to support this?
Thanks.

We have extactly the same problem with the SRP527W. Other Cisco small business products work like.
Cisco RV 120W
http://www.cisco.com/en/US/products/ps10852/index.html
Cisco WRV210
http://www.cisco.com/en/US/products/ps9929/index.html
We need a device with that supports one IPSec VPN and one ADSL interface and is easy to use like these devices.

Can a hosts be in the same subnet yet not be link local (trouble with Bonjour) ?
