MPLS-TE advertises 32 administrative groups (commonly referred to as
"colors" or "link colors") using the Administrative Group sub-TLV of
the Link TLV. This is defined for OSPFv2 (RFC3630), OSPFv3 (RFC5329)
and ISIS (RFC5305).
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.
