Description
Shows the state of the device session with the neighbor. The states are
from the device's perspective of the session, not the neighbor's
perspective. The state can be one of the following values:
• 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. 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.
• 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
messages with the neighbor.
If there is more BGP data in the TCP receiver queue, a plus sign (+) is also
displayed.
Shows the amount of time this session has been in its current state.
Shows the keepalive time, which specifies how often this device sends
KeepAlive messages to the neighbor.
Shows the hold time, which specifies how many seconds the device will
wait for a KeepAlive or Update message from a BGP4 neighbor before
deciding that the neighbor is dead.
Shows the time when the keepalive timer is set to expire.
Shows the time when the hold timer is set to expire.
Shows the minimum time elapsed between the route advertisements to
the same neighbor.
Shows whether the device has received confirmation from the neighbor
that the neighbor supports the dynamic refresh capability.
Shows the number of messages this device has sent to and received from
the neighbor. The display shows statistics for the following message types:
• Open
• Update
• KeepAlive
• Notification
• Refresh-Req
