The IETF TRILL base protocol [RFC6325] [RFC7780] has been extended with the RBridge Channel [RFC7178] facility to support transmission of typed messages (for example, Bidirectional Forwarding Detection (BFD) [RFC7175]) between two TRILL switches (RBridges) in the same campus and the transmission of such messages between RBridges and end stations on the same link. When sent between RBridges in the same campus, a TRILL Data packet with a TRILL Header is used, and the destination RBridge is indicated by nickname. When sent between a RBridge and an end station on the same link in either direction, a native RBridge Channel message [RFC7178] is used with no TRILL Header, and the destination port or ports are indicated by a Media Access Control (MAC) address. (There is no mechanism to stop end stations on the same link from sending native RBridge Channel messages to each other; however, such use is outside the scope of this document.)

          Transparent Interconnection of Lots of Links (TRILL):                     RBridge Channel Header Extension


   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.
