Note that: 

z 

Modifying the LDP neighbor liveness time will cause all LDP sessions and all LSPs based on the 

sessions to be removed and then reestablished. 

z 

For LDP sessions with MD5 authentication configured, you need to give the LDP neighbor liveness 

time a greater value so that the TCP connection can be reestablished. 

# Set the LDP neighbor liveness time to 100 seconds.

timer: Fault Tolerance (FT) reconnect time, in the range 60 to 300 seconds. 

Use the graceful-restart timer reconnect command to set the FT reconnect time.  

Use the undo graceful-restart timer reconnect command to restore the default. 

By default, the FT reconnect time is 300 seconds. 

Note that: 

z 

The FT reconnect time refers to the maximum time that the stale state flag will be preserved by the 

LSR after the TCP connection fails. 

z 

Modifying the FT reconnect time will cause all LDP sessions and all LSPs based on the sessions to 

be removed and then reestablished. 

# Set the FT reconnect time to 100 seconds.
