Multicast MAC ping
The destination MAC address of a multicast MAC ping packet is a multicast MAC address.
Multicast MAC ping provides the following functions:
–
Fault verification
Fault verification provided by multicast MAC ping is similar to that provided by 802.1ag
MAC ping.They are both used to check the reachability between the local and
destination devices by sending test packets. Unlike 802.1ag MAC ping, multicast MAC
ping can detect faults in links between multiple MEPs at a time.
Multicast MAC ping is applied to the networking where multiple MEPs are deployed.
Multicast MAC ping is initiated by the local MEP and responded to by the remote MEP.
