Abstract:
   In TRILL active-active access scenario, RPF check failure issue may
   occur when pseudo-nickname mechanism in [TRILLPN] is used. This
   draft describes a solution to the RPF check failure issue through
   centralized replication for BUM (Broadcast, Unknown unicast,
   Mutlicast) traffic. The solution has all ingress RBs send BUM
   traffic to a centralized node via unicast TRILL encapsulation. When
   the centralized node receives the BUM traffic, it decapsulates the
   traffic and forwards the BUM traffic to all destination RBs using a
   distribution tree established via the TRILL base protocol. 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 of RBv to perform the calculation.
