                 Spanning Tree Protocol (STP) Application            of the Inter-Chassis Communication Protocol (ICCP)


   The Inter-Chassis Communication Protocol (ICCP) supports an inter-    chassis redundancy mechanism that is used to support high network    availability.

   In this document, Provider Edge (PE) devices in a Redundancy Group    (RG) running ICCP are used to offer multihomed connectivity to    Spanning Tree Protocol (STP) networks to improve availability of the    STP networks.  The ICCP TLVs and usage for the ICCP STP application    are defined.
