Bidirectional MPLS-TP spoke SDPs with a configured pw-path-id can transport a mirrored service. Mirror services are not supported on static PWs with an MPLS-TP pw-path-id bound to an SDP that uses an RSVP-TE LSP.
Mirror services using MPLS-TP spoke SDPs can be configured using CLI in the context mirror-dest>remote-source. For both the CPM and IOM, this enables reuse of spokes for mirror services and other services such as pipes.
Control channel status signaling is supported with PW redundancy on spoke SDPs in a mirror context.
The following is an example of PW redundancy for a mirror service. In this case, MPLS-TP spoke SDPs are used.

Note that mirroring traffic is usually unidirectional, flowing from ‟source” nodes (B or C) to ‟destination” nodes (D or E). However, in case of MPLS-TP, the control channel status packets may flow in the reverse direction.
The following is an example of a mirror service configuration using MPLS-TP spoke SDPs:
