The show ip bgp command is used to display the contents of the BGP routing table. The output can be filtered to display entries for a specific prefix, prefix length, and prefixes injected through a prefix list, route map, or conditional advertisement. When changes are made to the network address, the network version number is incremented.

The show ip bgp command is used to display the contents of the BGP routing table. The output can be filtered to display entries for a specific prefix, prefix length, and prefixes injected through a prefix list, route map, or conditional advertisement.

The show ip bgp summary will show you the allowed Prefixes to be received only. The show ip bgp neighbor x.x.x.x received-routes will show you the total of the received prefixes, but you will see the symbol (>) for the allowed networks in your filter method.

By issuing the “show ip bgp summary” command we can see under neighbor column the IP address 10.10.12.2. This is the IP address of R2 with which R1 has established the peering relationship. We can see also that local AS number is 10. This means that both R1 and R2 are iBGP neighbors with each other, since the AS is the same.
