R0106-HP MSR Router Series MPLS Command Reference(V7)

314
specify both the start-address argument and the end-address argument, you specify a range of
destination addresses and the destination addresses increase in turn by the address-increment, starting
from the start-address to the end-address. The command performs a traceroute for each of the destination
addresses.
end-address: Specifies the end destination address. This address must be an address on subnet
127.0.0.0/8—a local loopback address.
address-increment: Specifies the increment value by which the destination address in the IP header
increases in turn. The value range is 1 to 16777215 and the default value is 1.
Examples
# 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.
