Validating LDP session reset

You can check the LDP session specific parameters to validate that a session has been successfully reset.

The following command shows two LDP sessions with neighbor 10.234.123.64.

device# show mpls ldp session
 Number of link LDP sessions: 1
 Number of Operational link LDP sessions: 1
 Number of targeted LDP sessions: 0
 Number of Operational targeted LDP sessions: 0
Peer LDP ID              State          Adj Used  My Role   Max Hold  Time Left
10.234.123.64            Operational    Link      Passive   36        33

The following command clears both the link and targeted LDP session with neighbor 10.234.123.64.

device# clear mpls ldp neighbor 10.234.123.64
device#
device# show mpls ldp session
Peer LDP ID              State          My Role   Max Hold  Time Left
10.234.123.64            Operational    Passive   36        33

This command shows that after waiting for roughly 20 seconds (depends on the hello or keepalive timer periodicity), both the LDP sessions are reestablished.

device# show mpls ldp session
Peer LDP ID              State          My Role   Max Hold  Time Left
10.234.123.64            Operational    Passive   36        33
