  Extended Administrative Groups in MPLS Traffic Engineering (MPLS-TE)

 Abstract

   MPLS Traffic Engineering (MPLS-TE) advertises 32 administrative    groups (commonly referred to as "colors" or "link colors") using the    Administrative Group sub-TLV.  This is defined for OSPFv2 (RFC 3630),    OSPFv3 (RFC 5329) and IS-IS (RFC 5305).

   This document adds a sub-TLV to the IGP TE extensions, "Extended    Administrative Group".  This sub-TLV provides for additional    administrative groups (link colors) beyond the current limit of 32.
