BGP Inquiry

[Brombeee]

Hi All

I have confusion in our network with regards in BGP.

In 1 router we have 2 ISP (main and backup) and both have BGP peer to ISP. When i issued "show ip bgp summary" it shows that only main ISP can received prefix the backup ISP shows up as 0 prefix but when i issue "show ip bgp neighbor (backup ISP IP) received-routes" i can see the full prefix from it. BGP config is the same for 2 ISP.

My first guess is that your configuration for the neighbors sets either weight or local preference to establish which neighbor is primary. Can you post your BGP configuration, including any route maps, prefix lists, and access lists used for BGP.

Also it might help if you post output of these commands

show ip bop sum

show ip bop neighbor

HTH
