Transparent Interconnection of Lots of Links (TRILL):
RBridge Channel Support
Abstract
This document specifies a general channel mechanism for sending
messages, such as Bidirectional Forwarding Detection (BFD) messages,
between Routing Bridges (RBridges) and between RBridges and end
stations in an RBridge campus through extensions to the Transparent
Interconnection of Lots of Links (TRILL) protocol.

1. Introduction
RBridge campuses provide transparent least-cost forwarding using the
Transparent Interconnection of Lots of Links (TRILL) protocol that
builds on Intermediate System to Intermediate System (IS-IS) routing
[IS-IS] [RFC1195] [RFC7176]. Devices that implement TRILL are called
