[j-nsp] Ethernet OAM, specifically CFM

[Humair Ali]

Actually CFM would be appropriate with what Chip is trying to achieve,

CFM monitor a maintenance session end to end and works a vlan or link level.

Why not monitor Cust Rtr interface to MX1 accross the bridge network  via
CFM and have an action profile assign to it ?

or monitor Cust Rtr 1 to remote end Cust Rtr 2 CFM , since usually you
would want to use CFM to guarantee a service.
