                 TRILL: RBridge Channel Tunnel Protocol
                <draft-ietf-trill-channel-tunnel-07.txt>

Abstract

   The IETF TRILL (Transparent Interconnection of Lots of Links)
   protocol includes an optional mechanism, called RBridge Channel, that
   is specified in RFC 7178, for the transmission of typed messages
   between TRILL switches in the same campus and between TRILL switches
   and end stations on the same link. This document specifies two
   optional extensions to the RBridge Channel protocol: (1) A standard
   method to tunnel a variety of payload types by encapsulating them in
   an RBridge Channel message; and (2) A method to support security
   facilities for RBridge Channel messages. This document updates RFC
   7178.

INTERNET-DRAFT                             TRILL: RBridge Channel Tunnel

1. Introduction

   The IETF TRILL base protocol [RFC6325] has been extended with an
   optional RBridge Channel [RFC7178] facility to support transmission
   of typed messages (for example BFD (Bidirectional Forwarding
   Detection) [RFC7175]) between two TRILL switches (RBridges) in the
   same campus and between RBridges and end stations on the same link.
   When sent between RBridges in the same campus, a TRILL Data packet
