BGP4 neighbor information (Continued)
Displays...
The description you gave the neighbor when you configured it on the
device.
The state of the router's session with the neighbor. The states are from
this router's perspective of the session, not the neighbor's perspective.
The state values are based on the BGP4 state machine values described
in RFC 1771 and can be one of the following for each router:
•
•
•
•
•
ACTIVE – BGP4 is waiting for a TCP connection from the neighbor.
If the state frequently changes between CONNECT and ACTIVE, there
may be a problem with the TCP connection.
•
•
•
NOTE: If there is more BGP data in the TCP receiver queue, a plus sign
The amount of time this session has been in its current state.
The keep alive time, which specifies how often this router sends keep
alive messages to the neighbor. Refer to
and hold time"
The hold time, which specifies how many seconds the router will wait for
a KEEPALIVE or UPDATE message from a BGP4 neighbor before deciding
that the neighbor is dead. Refer to
hold time"
The name of the peer group the neighbor is in, if applicable.

IDLE – The BGP4 process is waiting to be started. Usually, enabling
BGP4 or establishing a neighbor session starts the BGP4 process.
A minus sign (-) indicates that the session has gone down
and the software is clearing or removing routes.
ADMND – The neighbor has been administratively shut down. Refer
to "Administratively shutting down a session with a BGP4 neighbor"
on page 771.
A minus sign (-) indicates that the session has gone down
and the software is clearing or removing routes.
CONNECT – BGP4 is waiting for the connection process for the TCP
neighbor session to be completed.
OPEN SENT – BGP4 is waiting for an Open message from the
neighbor.
OPEN CONFIRM – BGP4 has received an OPEN message from the
neighbor and is now waiting for either a KEEPALIVE or
NOTIFICATION message. If the router receives a KEEPALIVE
message from the neighbor, the state changes to Established. If
the message is a NOTIFICATION, the state changes to Idle.
ESTABLISHED – BGP4 is ready to exchange UPDATE messages with
the neighbor.
(+) is also displayed.
If you display information for the neighbor using the show ip bgp
neighbor <ip-addr> command, the TCP receiver queue value will
be greater than 0.
