Transparent Interconnection of Lots of Links (TRILL)
Transparent Transport over MPLS
Abstract
This document specifies methods to interconnect multiple TRILL
(Transparent Interconnection of Lots of Links) sites with an
intervening MPLS network using existing TRILL and VPLS (Virtual
Private LAN Service) standards. This document addresses two
problems: 1) providing connection between more than two TRILL sites
that are separated by an MPLS provider network and 2) providing a
single logical virtualized TRILL network for different tenants that
are separated by an MPLS provider network.
