EIGRP ASA 5510 and 1841 ISR

Greetings.

Our network setup looks like this:

ASA 5510 --->> E0/1 (1841 ISR) E0/0 --->> Catalyst Switch

We've recently added an ASA 5510 to the network to replace the old hardware firewall. We have multiple VLANs setup on E0/0 of the 1841. I've attempted to configure EIGRP on the ASA and the ISR so that they would share the routing information between themselves but it didn't work. When I checked for neighbours, none were discovered/

Is it possible to do EIGRP this way?

Can you also confirm your ASA is not -

1) running in multiple context mode

2) running in transparent mode

Re: EIGRP ASA 5510 and 1841 ISR

So 192.168.15.x is the network connecting the ASA to the router ?

Is there any reason you have auto-summary on ? if not can you turn it off on both devices eg.

router eigrp

no auto-summary

also have you tried to debug eigrp on the router to see what it thinks is happening ?

Hello Felix,

EIGRP support has been added but it was not present in first ASA software versions

see

http://www.cisco.com/en/US/products/ps6120/products_configuration_example09186a008086ebd2.shtml

you need version 8.0 or better for EIGRP support on ASA

Hope to help

Can you post EIGRP config for firewall and router ?

This seemed to be it. The routes have showed up.

Thank you both for taking the time out to look at and respond to my question. I appreciate it very much.

The ASA is running in routed mode and single context mode.
