MPLS-TP PWs are supported in Epipe, Apipe, and Cpipe VLLs and Epipe spoke termination on IES/VPRN and VPLS, I-VPLS, and B-VPLS on the 7450 ESS and 7750 SR only.
This section describes how SDPs and spoke-SDPs are used with MPLS-TP LSPs and static pseudowires with MPLS-TP OAM. It also describes how to conduct test service throughput for PWs, using lock instruct messages and loopback configuration.
