BGP Selection -- multiple route-reflectors

$
0
0

I am having trouble trying to figure out the selection via two route-reflectors (matching IGP costs).  Hopefully someone can help with this. Thanks.

 

This is a BGP mini-lab I built in gns3.  

What I have done (without any effect):

  • raised/lowered bgp router-ids
  • raised/lowered bgp cluster-ids
  • raised/lowered OSPF router-ids

 

Here is the output after changing router-ids and cluster-ids:

Client-B(config)#do sh ip bgp 22.22.22.0
BGP routing table entry for 22.22.22.0/24, version 66
<snip>
  Local
    100.2.0.100 (metric 20) from 100.3.0.1 (111.111.111.111)
      Origin IGP, metric 0, localpref 100, valid, internal
      Originator: 22.22.22.22, Cluster list: 111.111.111.111
  Local
    10.2.0.100 (metric 20) from 10.3.0.1 (2.2.2.2)
      Origin IGP, metric 0, localpref 100, valid, internal, best
      Originator: 22.22.22.22, Cluster list: 2.2.2.2
