CFM over double tagged end-points

Domain double-tagged support for CFM enables up and down MEP at a double-tagged provider edge. For a Bridge Domain double tagged port to advertise CFM, the CLI command must specify the inner VLAN while configuring the MEP using the mep command as follows.

For more information on the command, please refer the SLX-OS Command Reference guide.

The show cfm command displays the inner vlan-id for MEP as follows.
