Configuring the LDP Keepalive Timeout
After an LDP session is established, messages must be exchanged periodically to ensure that the session is still working. The keepalive timeout defines the amount of time that the neighbor LDP node waits before deciding that the session has failed. This value is usually set to at least three times the keepalive interval. The default is 30 seconds.
To modify the keepalive interval, include the keepalive-timeout statement:
keepalive-timeout seconds;
For a list of hierarchy levels at which you can include this statement, see the statement summary section for this statement.
The value configured for the keepalive-timeout statement is displayed as the hold time when you issue the show ldp session detail command.
