This document specifies an inter-chassis communication protocol (ICCP) that enables PE redundancy for Virtual Private Wire Service (VPWS) and Virtual Private LAN Service (VPLS) applications. The protocol runs within a set of two or more PEs, forming a redundancy group, for the purpose of synchronizing data amongst the systems. It accommodates multi-chassis attachment circuit as well as pseudowire redundancy mechanisms.
