Router2#
Use the ping command to verify if Ethernet CFM loopback messages are successfully sent and received
between the routers:
Router#ping ethernet mpid 100 domain customer service customer1101 cos 5
Type escape sequence to abort.
Sending 5 Ethernet CFM loopback messages to 8843.e154.6f01, timeout is 5 seconds:!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
Router#
Use the traceroute command to send the Ethernet CFM traceroute messages:
Router#traceroute ethernet mpid 100 domain customer service customer1101
Type escape sequence to abort. TTL 64. Linktrace Timeout is 5 seconds
Tracing the route to 8843.e154.6f01 on Domain customer, Level 7, service customer1101,
