Hi Stewart,

Yes, it works with both LDP and RSVP-TE (or other signaling protocols). This is based on the PWE3 architecture where PWE3 layer and PSN layer are decoupled. If PSN is MPLS, all we need is an MPLS tunnel to the primary (or protected) PE, and an MPLS bypass tunnel from the PLR to the protector. The two tunnels may be LDP or RSVP-TE (or another protocol). The context ID defined in this draft can be used to facilitate the setup of these tunnels.


Thanks,

/Yimin

Yimin

A question before I reply in detail

Does this work over both an LDP signaled MPLS layer and an RSVP-TE signaled MPLS layer?
