[c-nsp] OAM/CFM question on IOS-XR

Hi Herro,

Disclaimer: I have no experience with configuring 802.1ag OAM on Cisco, but have been experimenting with it extensively on Brocade equipment.

Unfortunately not. The OAM frame will be marked with a label (or multiple labels) at the PE which will cause the intermediate LSRs to forward the frame based on the label, without processing the OAM payload.

This I won’t be able to answer, but it won’t surprise me if this indeed isn’t possible, seeing as MIP’s on LSR’s are actually pretty useless (at least to the circuits running over the MPLS backbone).
