Hello Luis
If you issue the show ip bgp neighbors command using the received-routes keyword and you don’t have soft-reconfig configured, then you will get the following result (I just tested it out…):
R1#show ip bgp neighbors 192.168.12.2 received-routes
% Inbound soft reconfiguration not enabled on 192.168.12.2
R1#
So the command can only be used if soft reconfig is configured. However, you can use the following command:
R1#show ip bgp neighbors 192.168.12.2 routes
This command will show you the routes received and accepted from that particular neighbour, and includes any alterations that have been made using inbound policies. When soft reconfig is not configured, there is no way to see the raw BGP information that has been sent from the neighbor since that info is not stored anywhere.
I hope this has been helpful!
