Displaying BGP4+ information

This display shows the following information.

TABLE 108 BGP4+ neighbor configuration information and statistics

This field... Displays...

IP Address The IPv6 address of the neighbor.

AS The AS in which the neighbor resides.

EBGP or IBGP Whether the neighbor session is an IBGP session, an EBGP session, or a confederation EBGP

session:

• EBGP – The neighbor is in another AS.

• EBGP_Confed – The neighbor is a member of another sub-AS in the same confederation.

• IBGP – The neighbor is in the same AS.

RouterID The neighbor’s router ID.

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 /jointfilesconvert/1441120/bgp neighbor

ipv6-address 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.

Messages Sent

and Received

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
