Abstract

In some scenarios, MPLS Transport Profile (MPLS-TP) pseudowires (PWs)(RFC 5921) may be statically configured when a dynamic control planeis not available. A fast protection mechanism for MPLS-TP PWs isneeded to protect against the failure of an Attachment Circuit (AC),the failure of a Provider Edge (PE), or a failure in the PacketSwitched Network (PSN). The framework and typical scenarios of dual-homing PW local protection are described in RFC 8184. This documentproposes a dual-homing coordination mechanism for MPLS-TP PWs that isused for state exchange and switchover coordination between the dual-homing PEs for dual-homing PW local protection.
