Cisco 870 with BVI not pingable

Hello,

I have the following topology, where the cisco router job is to let pass through data between the hosts behind the switch and the gateway which grants access to the internet.

The configuration is working fine, hosts inside the network can access internet and are able to see each other and the gateway, although what I would like to do is to make also the cisco router reachable by ping/ssh.

Up to this moment a ping to 192.168.0.201 from inside the network do not succeed, and neither a ping from the cisco against one of the hosts/gateway. Adding static arp entries to the cisco did not help.

Given the below configuration, are there additional changes to do to be able to continue the passthrough task and at the same time to talk with the internal hosts?

Hi,

Since you are bringing the 2 interfaces together, can you try and disable "ip routing" "no ip routing" and test again?

Re: Cisco 870 with BVI not pingable

Like Reza when I read the original post and realized that the original poster really wants to use the router just to do bridging i thought of suggesting disabling ip routing. I am not sure if the original post has been edited to reflect that suggestion. But as I read the config in the original post ip routing is disabled there. And in retrospect I wonder if that is part of the problem. It is quite possible to disable ip routing and to enable bridging on each interface. I have done this (in the lab) and it works fine. But configuring rib and configuring interface BVI is different from just bridging. I wonder if rib and BVI need ip routing enabled.

 

And I think that Paul is spot on in suggesting bridge 102 route ip.

Hi Everybody,

thank you for your replies, i'll try with the bridge command and get back to you (probably next week since the guy who is physically at the location is on vacation).
