This field Displays
State The state of device sessions with each neighbor. The states are from this perspective
of the device, not the neighbor. State values are based on the BGP4 state machine
values described in RFC 1771 and can be one of the following for each device:
• 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.
• CONNECT - BGP4 is waiting for the connection process for the TCP neighbor
session to be completed.
• ACTIVE - BGP4 is waiting for a TCP connection from the neighbor. Note : If the
state frequently changes between CONNECT and ACTIVE, there may be a
problem with the TCP connection.
• 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 device
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 packets with the neighbor.
Operational States:
Additional information regarding the operational states of the BGP4 states described
above may be added as described in the following:
• (+) - is displayed if there is more BGP4 data in the TCP receiver queue. Note : If
you display information for the neighbor using the show ip bgp neighborip-addr
command, the TCP receiver queue value will be greater than 0.
• (-) - indicates that the session has gone down and the software is clearing or
removing routes.
• (*) - indicates that the inbound or outbound policy is being updated for the peer.
• (s) - indicates that the peer has negotiated restart, and the session is in a stale
state.
• (r) - indicates that the peer is restarting the BGP4 connection, through restart.
• (^) - on the standby MP indicates that the peer is in the ESTABLISHED state and
has received restart capability (in the primary MP).
• (<) - indicates that the device is waiting to receive the "End of RIB" message the
peer.
• (p) - indicates that the neighbor ribout group membership change is pending or in
progress
• () - indicates that the device is waiting to receive the "End of RIB" message the peer
Time The time that has passed since the state last changed.
Accepted The number of routes received from the neighbor that this device installed in the BGP4
route table. Usually, this number is lower than the RoutesRcvd number. The difference
indicates that this device filtered out some of the routes received in the UPDATE
messages.
