Technical Summary This document specifies the IS-IS extensions necessary to support link state routing to any protocols running directly over layer 2. While supporting this concept involves several pieces, this document only describes extensions to IS-IS. Furthermore, the TLVs described in this document are generic layer 2 additions and specific ones as needed are defined in the IS-IS technology specific extensions. Working Group Summary Issues arose as this document, draft-ietf-isis-trill and draft-ietf-isis-ieee-aq were originally one document. It was felt during review that draft-ietf-isis-trill and draft-ietf-isis-ieee-aq were sufficiently different that there needed to be a "base" document (this one) and two separate technology documents. The opinion of the ISIS WG it is unfortunate that there could not be one solution for layer2 routing in ISIS but, this decision was not within the remit of the ISIS WG. Document Quality There are multiple, interoperable implementations. Personnel David Ward is the Document Shepherd for this document. Stewart Bryant is the Responsible Area Director.
