Abstract:
   In TRILL active-active access scenario, RPF check failure issue may
   occur when pseudo-nickname mechanism in [RFC7781] is used. This
   draft describes a solution to resolve the RPF check failure issue
   through centralized replication. All ingress RBridges send BUM
   (Broadcast, Unknown unicast and Mutlicast) traffic to a centralized
   node with unicast TRILL encapsulation. When the centralized node
   receives the BUM traffic, it decapsulates the packets and forwards
   them to all destination RBridges using a distribution tree
   established as per TRILL base protocol[RFC6325]. To avoid RPF check
   failure on a RBridge sitting between the ingress RBridge and the
   centralized replication node, some change of RPF calculation
   algorithm is required. RPF calculation on each RBridge should use
   the centralized node as ingress RB instead of the real ingress
   RBridge which is denoted as RBv in [RFC7781] to perform the
   calculation.
