Header
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 7-23 explains the fields for each neighbor entry.
Table 7-23: 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
10.10.14.51 4 100 93 120 0 0 0 00:42:16 0
• The neighbor has the IP address 10.10.14.51 and AS number 100.
• The neighbor uses BGP version 4.
• 93 messages have been received.
• 120 messages have been sent.
• The BGP routing table version is 0.
• There are no received messages waiting in the input queue for further processing.
• There are no messages waiting in the output queue to be sent.
• The connection has been up for 0 hours, 42 minutes and 53 seconds.
• The local router has received no prefixes from this neighbor.
