detail extensive

Active

Whether the local router is playing the active role in the session and during session establishment.

detail extensive

Maximum PDU

Maximum PDU size for the session.

detail extensive

Hold time

Time remaining until the session will be closed, in seconds. This value corresponds to the one configured using the keepalive-timeout statement configured at the [edit protocols ldp] hierarchy level.

detail extensive

Neighbor count

Number of neighbors that are contributing to the session.

detail extensive

Keepalive interval

Keepalive interval, in seconds.

detail extensive

Connect retry interval

TCP connection retry interval, in seconds.

detail extensive

Local address

Local transport address.

detail extensive

Remote address

Remote transport address.

detail extensive

Up for

Time that this session has been up.

detail extensive

Last down

Time since the session last went down.

detail extensive

Reason

Reason the session went down:

• Aborted graceful restart
• Authentication key was changed
• Bad type length value (TLV)
• Bad protocol data unit (PDU) packets
• Command-line interface (CLI) command
• Connect time expired
• Connection error
• Connection reset
• Error during initialization
• Hold time expired
• No adjacency or all adjacencies down
• Notification received
• Received notification from peer
• Unexpected End of File (EOF)
• Unknown reason

detail extensive

Number of session flaps

Number of times the session changes from up to down.

detail extensive

Restarting

LDP is in the process of gracefully restarting.

detail extensive

restart complete in nnn msec

Amount of time (in milliseconds) remaining until graceful restart is declared complete.

detail extensive

Local

Information about graceful restart for the local end of an LDP session. Graceful restart and helper mode are independent.

• Restart—Status of the grateful restart feature at the local end of the LDP session: enabled or disabled.
• Helper mode—Status of the helper mode feature at the local end of the LDP session: enabled or disabled. When this feature is enabled, the local end of the LDP session can help the restarting router with its LDP restart procedures.
• Reconnect time—Amount of time to wait from when a restart is initiated until the router can exchange LDP messages with its neighbors. The default is 60000 msec and is not configurable. (Reconnect timeout refers to "FT Reconnect timeout" in draft-ietf-mpls-ldp-restart-06, Internet Draft Graceful Restart Mechanism for LDP.)

detail extensive

Remote

Information about graceful restart at the remote end of an LDP session. Graceful restart and helper mode are independent.

• Restart—Status of the grateful restart feature at the remote end of the LDP session: enabled or disabled.
• Helper mode—Status of the helper mode feature at the remote end of the LDP session: enabled or disabled. When this feature is enabled, the remote end of the LDP session can help the restarting router with its LDP restart procedures.
• Reconnect time—Amount of time in milliseconds from when a restart is initiated until the remote router can exchange LDP messages with its neighbors.

detail extensive

Local maximum recovery time

Amount of time during which the restarting node attempts to recover its lost states with help from its neighbors (in milliseconds).

detail extensive

Next-hop addresses received

Next-hop addresses received on the session.

detail extensive

Queue depth

Number of messages that are queued for sending to the peers in the group.

extensive

Message type

Type of message being sent.

• Total—Messages sent and received during the lifetime of the session.
• Last 5 seconds—Messages sent and received during the current session.
