This document specifies an Inter-Chassis Communication Protocol (ICCP) that enables Provider Edge (PE) device 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 among the systems.It accommodates multi-chassis attachment circuit redundancy mechanisms as well as pseudowire redundancy mechanisms.
