State

The state of the device’s session with the neighbor. The states are from the perspective
of the session, not the neighbor’s perspective. The state values can be one of the
following:

• 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+4 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.

NOTE
If you display information for the neighbor using the show ipv6 bgp neighboraddress> command, the TCP receiver queue value will be greater than 0.

Time

The amount of time this session has been in its current state.

KeepAliveTime

The keep alive time, which specifies how often this device sends keep alive messages
to the neighbor.

HoldTime

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.

RefreshCapability

Whether the device has received confirmation from the neighbor that the neighbor
supports the dynamic refresh capability.
