Field Description

State 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.

Time Shows the amount of time this session has been in its current state.

KeepAliveTime Shows the keepalive time, which specifies how often this device sends KeepAlive

messages to the neighbor.

HoldTime 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.

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 device has received confirmation from the neighbor that the

neighbor supports the dynamic refresh capability.
