Redistributed bgp-to-eigrp routes not appearing in ASA route table

Hello,

We have a 2951 router running BGP whose routes we redistribute into EIGRP for an adjacent 3560 switch. The switches table shows all the redistributed routes (D EX) however the ASA to which that switch is connected to does not show the additional routes, only the local LAN subnet learned from the neighboring switch over EIGRP. See below:

Switch eigrp configuration and route table showing redistributed routes learned from neighboring 2951 router:

Re: Redistributed bgp-to-eigrp routes not appearing in ASA route

I believe your issue is in the eigrp stub command, I have never set up a stub configuration so I am not 100% familiar with what it intentions are.  This link seems to discuss all the different scenrios and config examples of such.

http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/eigrpstb.html

For my own sanity sake I would remove that line and see if that affects the announcement.

Redistributed bgp-to-eigrp routes not appearing in ASA route tab

Thanks for the reply Rick. That's actually one of the first things I tried when I noticed the issue. Unfortunately I get the following error when trying to remove that bit of configuration:

EIGRP is restricted to stub configurations only on this platform.

At first I only had the default 'connected' and 'summary' parts of the stub configuration. Then I found the 'redistribute' command which I thought for sure would solve my problem by broadcasting the redistributed external EIGRP routes to the ASA....but no luck.
