Abstract:
   TRILL facilitates loop free connectivity to non-TRILL legacy
   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. Mission critical operations such as High
   Performance Data Centers require an active-active load sharing
   model. The Active-Active load-sharing model can be accomplished by
   representing any given non-TRILL legacy network with a single
   virtual RBridge. Virtual representation of the non-TRILL legacy
   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 provides flexibility to RBridges in selecting desired
   path of association to a given TRILL multi-destination distribution
   tree. This document updates RFC 6325.
