# Trace the path that the LSP (for FEC 5.5.5.9/32) traverses from the ingress node to the egress node.
Specify the IP header destination address range as 127.1.1.1 to 127.1.1.2 and set the address increment
value to 1. With the configurations, the device performs a traceroute for 127.1.1.1 and 127.1.1.2.
