Abstract Abstract
This document specifies the IS-IS extensions necessary to support This document specifies the IS-IS extensions necessary to support
link state routing to any protocols running directly over layer 2. link state routing to any protocols running directly over layer 2.
While supporting this concept involves several pieces, this document While supporting this concept involves several pieces, this document
only describes extensions to IS-IS. Furthermore, the TLVs described only describes extensions to IS-IS. Furthermore, the TLVs described
in this document are generic layer 2 additions and specific ones as in this document are generic layer 2 additions and specific ones as
needed are defined in the IS-IS technology specific extensions. We needed are defined in the IS-IS technology specific extensions. We
leave it to the systems using these IS-IS extensions to explain how leave it to the systems using these IS-IS extensions to explain how
