Many of these link attributes can be used for applications other than MPLS Traffic Engineering or GMPLS. This document defines how to distribute such attributes in OSPFv2 and OSPFv3 for applications other than MPLS Traffic Engineering or GMPLS. @@ -30,65 +30,53 @@ Internet-Drafts are working documents of the Internet Engineering Task Force (IETF).
