Parameters
hop-number: Specifies the maximum hop count for loop detection, in the range of 1 to 32.
Usage guidelines
LDP adds a hop count in a label request or label mapping message. The hop count increments by 1 on
each LSR. When the hop count reaches the maximum hop count configured by this command, LDP
considers that a loop occurs and terminates LSP establishment.
Set a proper maximum hop count according to the number of LSRs in your network. For example, set a
smaller maximum hop count in small networks to allow for fast loop detection; set a bigger maximum hop
count in large networks to make sure that LSPs can be successfully established.
Examples
# Set the maximum hop count to 25 for loop detection in the public network.
