Internet Engineering Task Force (IETF) D. Eastlake 3rd Request for Comments: 7978 Huawei Updates: 7178 M. Umair Category: Standards Track IPinfusion ISSN: 2070-1721 Y. Li Huawei September 2016 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. Status of This Memo This is an Internet Standards Track document. This document is a product of the Internet Engineering Task Force (IETF). It represents the consensus of the IETF community. It has received public review and has been approved for publication by the Internet Engineering Steering Group (IESG). Further information on Internet Standards is available in Section 2 of RFC 7841.
