EIGRP ASA 5510 and 1841 ISR

Answered Question

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?

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 ?

Can you also confirm your ASA is not -


1) running in multiple context mode


2) running in transparent mode

Can you post EIGRP config for firewall and router ?
