TblVer

Last version of the BGP database that was sent to a neighbor.

InQ

Number of messages from a neighbor waiting to be processed.

OutQ

Number of messages waiting to be sent to a neighbor.

Up/Down

Length of time in (hh:mm:ss) that the BGP session has been in Established state, or the time since the session left Established state, if it is not established.

St/PfxRcd

If the BGP session is not established, the current state of the session. If the session is established, the number of prefixes the router has received from the neighbor.

If the number of prefixes received exceeds the maximum allowed (as set by the maximum-prefix command), “(PfxRcd)” appears.

If the connection has been shut down using the shutdown command, “(Admin)” appears.

If the neighbor is external and it does not have an inbound and outbound policy configured for every address family, an exclamation mark (!) is inserted at the end of the state when using the route-policy ( BGP ) command.

If the connection has been shut down due to out of memory (OOM), “(OOM)” appears.
