Extended Administrative Groups in MPLS Traffic Engineering
RFC 7308, “Extended Administrative Groups in MPLS Traffic Engineering”, is a Proposed Standard document published in July 2014 by E. Osborne. The canonical text is published by the RFC Editor.
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.
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
