Problem redistributing bgp into eigrp

Velimir Filipov

Hello.

I have a cisco 3745 running IOS (tm) 3700 Software (C3745-ADVIPSERVICESK9-M), Version 12.3(20), RELEASE SOFTWARE (fc2).

I have a problem redistributing routes learned via BGP into the EIGRP. Here is my configuration.

router eigrp 100
redistribute bgp 999 metric 200 1 255 1 1500 route-map only-private-addresses
network 10.0.0.0
network 172.16.0.0
network 192.168.0.0 0.0.255.255
maximum-paths 1
no auto-summary
eigrp router-id 192.168.96.1
eigrp kill-everyone
no eigrp log-neighbor-changes
no eigrp log-neighbor-warnings

Router#show route-map only-private-addresses
route-map only-private-addresses, permit, sequence 10
  Match clauses:
    ip address (access-lists): private-addresses
  Set clauses:
  Policy routing matches: 0 packets, 0 bytes

Router#show ip access-lists private-addresses
Standard IP access list private-addresses

    40 permit 2.2.2.2 (1 match)
    10 permit 10.0.0.0, wildcard bits 0.255.255.255 (138 matches)
    20 permit 172.16.0.0, wildcard bits 0.15.255.255 (171 matches)

    30 permit 192.168.0.0, wildcard bits 0.0.255.255 (92 matches)

I have a bgp neighbour advertising the prefix 2.2.2.2/32

Router#show ip route 2.2.2.2
Routing entry for 2.2.2.2/32
  Known via "bgp 999", distance 200, metric 1000, type internal
  Redistributing via eigrp 100
  Last update from 10.15.1.6 00:32:17 ago
  Routing Descriptor Blocks:
  * 10.15.1.6, from 10.15.1.6, 00:32:17 ago
      Route metric is 1000, traffic share count is 1
      AS Hops 0

Even though it says "Redistributing via eigrp 100", the prefix just wont show up in the eigrp topology, and its not seen by the other routers participating in the eigrp..

Router#show ip eigrp topology 2.2.2.2/32
% IP-EIGRP (AS 100): Route not in topology table

Any suggestions other than rebooting the router as thats not an option ?

Thanks in advance.

p.s. I have changed the BGP AS for security purposes.

You must rethink your solution.

By default, iBGP redistribution into IGP is disabled and from the output I noticed that the 2.2.2.2 prefix was learned via iBGP.

So, actually your config is working as intended. (by Cisco)

Leo, thank you so much for the fast and accurate answer.Its understandable why they made it this way.

I appreciate that there are people like you helping others, and sorry i guess i could have searched and read a little bit more instead of asking directly.

Best regards.

Hi,

Thanks for the rating. Always glad to be of help.

I must compliment you as well because this was one of the very few posts on this forum where all the info that's needed to solve the question was in the initial post. This speeds up the resolution process considerably.
