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.

vyatta@R1:~$ show ip bgp summary 
BGP router identifier 10.0.0.11, local AS number 100
RIB entries 23, using 1472 bytes of memory
Peers 4, using 10080 bytes of memory

After adding the eBGP peer 88.88.88.2 (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 88.88.88.2 shows “4” and “5” respectively. This shows that R1 has received four BGP messages from 88.88.88.2 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 10.0.0.44 or from 88.88.88.2. 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.
