Use the ttl command to configure the maximum number of hops a probe packet traverses in the 

network. 

Use the undo ttl command to restore the default. 

By default, the maximum number of hops that a probe packet can traverse in a network is 20. 

Note that after you configure the route-option bypass-route command, the maximum number of hops 

a probe packet traverses in the network is 1, and the ttl command does not take effect. 

# Configure the maximum number of hops that a probe request can traverse in a network as 16.
