The IETF has standardized TRILL (TRansparent Interconnection of Lots of Links), a protocol for least cost transparent frame routing in multi-hop networks with arbitrary topologies and link technologies, using link-state routing and encapsulation with a hop count. The TRILL base protocol standard supports labeling of TRILL data with up to 4K IDs. However, there are applications that require more fine- grained labeling of data. This document updates RFC 6325 by specifying extensions to the TRILL base protocol to accomplish this.
