MPLS ping is a utility just like our old ipv4 ping in the hop to hop ip routing scenarios. The only difference is that it tells you that everything is fine in MPLS label switch path. In mpls label switch path you cannot rely on normal ping as it is possible that normal ping is working… Read More How MPLS Ping, MPLS Traceroute , MPLS Multipath trace can help in MPLS troubleshooting.
