11.5.2.1 Interoperability between a Y.1731 MEP and 802.1ag MEPs
In general, an 802.1ag MEP cannot interoperate correctly with a Y.1731 MEP; that is, they cannot
correctly exchange CCM messages. Their respective standards do not provide compatibility
methods.
The Canoga Perkins 9145E NID does, however, provide a configuration method that will allow
interoperability between a Y.1731 MEP and an 802.1ag MEP operating in the same administra-
tive domain at the same level.
