State Shows the state of the router session with the neighbor. The states are from the router’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: When 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. When the router receives a
KeepAlive message from the neighbor, the state changes to ESTABLISHED. When the
message is a Notification, the state changes to IDLE.
•
ESTABLISHED – BGP4 is ready to exchange Update messages with the neighbor.
When there is more BGP data in the TCP receiver queue, a plus sign (+) is also displayed.
Time Shows the amount of time this session has been in its current state.
KeepAliveTime Shows the keepalive time, which specifies how often this router sends KeepAlive messages to
the neighbor.
HoldTime Shows the hold time, which specifies how many seconds the router waits for a KeepAlive or
Update message from a BGP4 neighbor before deciding that the neighbor is dead.
KeepAliveTimer
Expire Shows the time when the KeepAlive timer is set to expire.
HoldTimer Expire Shows the time when the hold timer is set to expire.
Minimal Route
Advertisement
Interval Shows the minimum time elapsed between the route advertisements to the same neighbor.
RefreshCapability Shows whether the router has received confirmation from the neighbor that the neighbor
supports the dynamic refresh capability.

and Received Shows the number of messages this router has sent to and received from the neighbor. The
display shows statistics for the following message types:
•
Open
