BGP Received Prefix from Peer

BubbleGang · ‎10-20-2010

Hi All,

Is there a way to know how many prefix a certain peer advertises to my router even though the soft-reconfiguration inbound is not configured in bgp? We disabled soft reconfiguration because it consumes a lot of CPU.

ISP-RTR#sho ip bgp neighbors 10.1.1.2 received-routes
% Inbound soft reconfiguration not enabled on 10.1.1.2

Regards,

sh ip bgp summary will list the details fo the neighbors and the last column lists you the prefixes learned from each neigbor.Another thing you see is the sh proc cpu history | include BGP will help you find if BGP is consuming CPU or not.

Ok njangale im confused. Before when the soft reconfiguration was in place and i issue the show ip bgp neig received-routes command it show that we are receiving 300000+ prefixes from our ISP. But the number of prefix received does not match when i issue the show ip bgp summary command.

ISP1>sho ip bgp neighbors 10.1.1.1 received-routes
% Inbound soft reconfiguration not enabled on 10.1.1.1

Note: It showed 300000+ prefix
