Displaying LDP information

2

NOTE

The key displayed using the command, show mpls ldp session detail is the one configured for that
session. This key may not be the one which is “in use” by that session as the session may have been
established prior to the change in the configured key. When the session is already in the established
state, any change in the authentication key takes effect during the next incarnation of the LDP
session.

For each established LDP session, the command displays the following information:

TABLE 52

Output from the show mpls ldp session detail command

This field...

Displays...

Peer LDP ID

The LDP identifier of the peer LSR. The first four octets identify the peer LSR IP
address; the second two octets identify a label space on the LSR. For LSRs
that use per-platform label spaces, the second two octets are always zero.

Local LDP ID

This LSRs LDP identifier.

State

The LDP session state, as defined in RFC 3036. This can be “Nonexistent”,
“Initialized”, “OpenRec”, “OpenSent”, or “Operational”.

Adj

Whether the session was established using the Link adjacency (basic
discovery) or the Targeted discovery (extended discovery).

Role

Whether this LSR is playing an “active” or “passive” role in session
establishment.

Next keepalive

When this LDP session is established, the amount of time, in seconds, before
the next KeepAlive message is sent to the active peer. When this LSR is the
active peer, prior to establishing a session with the passive peer, the text “Next
Initialization” is displayed instead. The “Next Initialization” value indicates, in
seconds, when the next Initialization message is sent to the passive peer.

Hold time left

The amount of time, in seconds, before the LDP session times out when no
KeepAlive message is received from the peer.

Max hold time

The number of seconds that the “Hold time remain” counter is reset to once a
KeepAlive message is received from the peer.

Up Time

The Up Time is displayed in days, hours, minutes, and seconds. This line
appears only when the session is in Operational Up State.

KeepAlive interval

The amount of time the LSR waits for an LDP PDU from the peer. When this
amount of time passes without receiving an LDP PDU from the peer, the LDP
session is terminated.

MD5 Authentication Key

The MD5 authentication key is displayed in an encrypted form when the user
does not have the correct privileges. When the user has the correct
permission, it displays as clear text.

Neighboring interfaces

The interfaces where an LDP neighbor/adjacency relationship has been
established with the peer. When there are multiple connections between two
LDP-enabled peers, there can be multiple neighboring interfaces. When
applicable, the Neighboring Interface field displays a VE interface specified by
the vid variable.

TCP connection

The local and remote IP addresses and port numbers for the TCP connection
between the peers.
