Modifying the LDP recovery time may cause the original sessions to be 
reestablished. The LSPs based on the sessions will be removed and need to be 
reestablished.

hop-number: Hop count, in the range 1 to 32.

Use the hops-count command to set the maximum hop count for loop detection.

Use the undo hops-count command to restore the default.

By default, the maximum hop count for loop detection is 32.

Note that:

■

You must configure the command before enabling LDP on any interface.

■

The maximum hop count dictates how fast LDP detects a loop. Adjust this 
argument as required.
