Transparent Interconnection of Lots of Links (TRILL):
RBridge Channel Header Extension
Abstract
The IETF TRILL (Transparent Interconnection of Lots of Links)
protocol includes an optional mechanism (specified in RFC 7178)
called RBridge Channel for the transmission of typed messages between
TRILL switches in the same campus and the transmission of such
messages between TRILL switches and end stations on the same link.
This document specifies extensions to the RBridge Channel protocol
header to support two features as follows: (1) a standard method to
tunnel payloads whose type can be indicated by Ethertype through
encapsulation in RBridge Channel messages; and (2) a method to
support security facilities for RBridge Channel messages. This
document updates RFC 7178.
