BGP table clarification

Unanswered Question
Feb 10th, 2010

Hello All,

The output below is a bit confusing to me. I am expecting to only see one entry in the bgp table for the route below, but for some reason BGP shows two entries with the same path but different attribute values. Can anyone clarify this behavior.

BTW I do have a route-map that sets local-pref and weight values.

router#show ip bgp vpn4 vrf hello 192.168.100.7
BGP routing table entry for 13331:1:192.168.100.7/32, version 253538
Paths: (2 available, best #1, table hello)
  Advertised to update-groups:
     2
  11111 22222
    1x.x.x.x0 from 14.250.0.70 (1x.x.x.x6)
      Origin incomplete, localpref 150, weight 40000, valid, external, best
  11111 22222, (received-only)
    1x.x.x.70 from 14.250.0.70 (1x.x.x.x6)
      Origin incomplete, localpref 100, valid, external
router#

--- thanks in advance

I have this problem too.

Hi,

The output showing (received-only) means it was blocked by a filter policy you have configured (probably that route-map setting LP you said you have configured) but it is showing because you must have "soft-reconfiguration inbound" configured on that peer 1x.x.x.70.

Can you please show us the configuration, obviously hashing out any sensitive configurations. Is this peer a Route-Reflector or is it the direct peer?

HTH.

Thanks.

Joe,
