Title : Coordinated Multicast Trees (CMT) for TRILL

Abstract:
TRILL facilitates loop free connectivity to non-TRILL networks via
choice of an Appointed Forwarder for a set of VLANs. Appointed
Forwarders provide load sharing based on VLAN with an active-standby
model. High performance applications require an active-active load-
sharing model. The Active-Active load-sharing model can be
accomplished by representing any given non-TRILL network with a
single virtual RBridge. Virtual representation of the non-TRILL
network with a single RBridge poses serious challenges in multi-
destination RPF (Reverse Path Forwarding) check calculations. This
document specifies required enhancements to build Coordinated
Multicast Trees (CMT) within the TRILL campus to solve related RPF
issues. CMT, which only requires software upgrade, provides
flexibility to RBridges in selecting desired path of association to
a given TRILL multi-destination distribution tree. This document
updates RFC 6325.
