Its easier to see it with below summary command but yes you can verify with that command just look for the Established section and timer ----BGP state = Established, up for 5d01h
#sh ip bgp summ

The Up/Down section --- timer shows each neighbour is up 5 days 1 hour , if it was failed neighbour state it would say Idle/Active where the timer is now instead of giving uptime
The prefix is how many routes im pulling from ISP provider or from my ibgp neighbour connections
