BGP router identifier 10.10.15.50, local AS number 65000
1 BGP AS-PATH entries
0 BGP community entries
• The BGP router identifier is 10.10.15.50 and the local router AS number is 65000.
• The BGP table version tracks the local BGP table version. Any time the BGP best path algorithm executes, the table version increments.
• There is one BGP AS-PATH entry and no community entries.

Neighbor Entry Fields

Table 35 explains the fields for each neighbor entry.

Table 35.

neighbor entry fields

Field

Description

Neighbor

IP address of peer.

V

BGP version of peer.

AS

Autonomous system number of peer.

MsgRcvd

Messages received since the BGP connection was established.

MsgSent

Messages sent since the BGP connection was established.

TblVer

Last version of the local router’s BGP database advertised to the peer.

InQ

Received messages waiting in the input queue for further processing.

OutQ

Messages waiting in the output queue to be sent.

Up/Down

Connection up time and down time.

State/PfxRcd

If the TCP session is up and the BGP peers have formed an adjacency, this field shows how many prefixes have been received from the remote neighbor.

 

Other states:

 

Idle: The local router has not allocated resources for the peer connection, so incoming connection requests are refused

 

Idle (Admin): The peer has shut down

 

Idle (PfxCt): Prefix overflow

 

Idle (G-shut): Graceful shutdown

 

Connect: BGP is waiting for the TCP connection to complete

 

Active: the local router is trying to establish a TCP connection to the remote peer. You might see this if the local peer has been configured, but the remote peer is unreachable or has not been configured.

 

OpenSent: BGP is waiting for an open message from its peer

 

OpenConfirm: BGP received an open message from the peer and is now waiting for a keepalive or notification message. If BGP receives a keepalive message from the peer, the state changes to established. If the message is a notification, the state changes to idle.

 

Established: BGP is ready to exchange update, notification, and keepalive messages with its peer

 

Invalid: The session state is invalid

Neighbor Entry Example
