R1: show ip bgp summary

The following example shows the output of the show ip bgp summary command for router R1 at this stage of the configuration.

Total number of neighbors 4

After adding the eBGP peer (the BGP ID configured for the router connected to AS 200) to R1 we can see that the connection to the new peer is established (in the Up/Down field). This indicates that the peer was properly preconfigured for this connection.

Additionally, you may notice that the MsgRcvd and MsgSent fields for peer shows “4” and “5” respectively. This shows that R1 has received four BGP messages from and sent it five, which are associated with the connection to the peer (the show ip bgp neighbors command can be used to provide additional detail). Also, you can see that router R1 has received no route prefixes (PfxRcd column) from either or from This indicates that, though the BGP neighbors are communicating, they are not sending any prefixes. This is the way is should be at this point in the example as we have not yet configured routing announcements on any of the BGP peers.
