    abstract =  {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.},
