i have a situation where we have an ASA currently connected to a Cisco 3800 router
running EIGRP and everything works fine, i.e. eigrp neighbour is formed
and routes exchanged.
I need to move the ASA from the 3800 to our new data centre and connect it to a Cisco 4900-M running EIGRP.
I reconfigured the ASA to the new IP addressing scheme (to match the 4900-M) and included the new network statement in EIGRP.
I cabled the ASA to the 4900-M. Interfaces came up and EIGRP neighbour was formed. However, no routes were exchanged between devices. From the 4900 i could ping the ASA interface withou any problems. I debugged EIGRP on the 4900 and did not see anything that would cause them to not exchange routes. I have another device (3800) on the same subnet and the 4900 is able to exchange routes with it as is the ASA. There are no filters applied to the 4900-M or the ASA.
Has anyone seen a similar issue or have any ideas what the problem, could be? I had to back out the change and as soon as i reconfigured the original IP address on the ASA and moved it back to the old network everything worked fine again.
