Use the show ip bgp summary command to display a summary of the BGP route table.<br />
#show ip bgp summary<br />
The exact prefixes that are being transmitted and received are shown in this output. The o in<br />
front of the 172.16.70.0/30 route indicates it is a received route. For received routes to be<br />
exported to the route table, they must be the best valid route indicated with the *> for the<br />
received route.<br />
The following sample output of the show ip bgp summary command shows a summarized list of the<br />
configured BGP neighbors, as well as their status and statistics.<br />
#show ip bgp summary<br />
