Abstract:
   In TRILL active-active access, an RPF check failure issue may occur
   when using the pseudo-nickname mechanism specified in RFC 7781. This
   draft describes a solution to resolve this 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 RFC 6325. To avoid RPF check
   failure on a RBridge sitting between the ingress RBridge and the
   centralized replication node, some change in the RPF calculation
   algorithm is required. RPF calculation on each RBridge should use
   the centralized node as the ingress RBridge, instead of the real
   ingress RBridge, which is denoted as RBv in RFC 7781, to perform the
   calculation.
