VIAVI TestCenter: Is multicast destination supported on EOAM Loopback messages?
• Yes but only for ITU-T implementation. This is a specification issue. IEEE doesn't support multicast destination for Loopback messages.
• IEEE 802.1ag-2007
• 3.15 Loopback Message (LBM): A unicast CFM PDU transmitted by a MEP, addressed to a specific MP, in the expectation of receiving an LBR.
• ITU-T G.8013/Y.1731
• 7.2 Ethernet Loopback (ETH-LB)
• Ethernet Loopback function (ETH-LB) is used to verify connectivity of a MEP with a MIP or peer MEP(s). There are two ETH-LB types:
• Unicast ETH-LB
• Multicast ETH-LB
