This draft describes a solution to resolve this RPF check failure issue through centralized replication. All ingress RBridges send BUM (Broadcast, Unknown unicast and Multicast) 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 their 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 checks on each RBridge MUST be calculated as if the centralized node was the ingress RBridge, instead of being calculated using the actual ingress RBridge.}, }
