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 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 should be
calculated as if the centralized node was the ingress RBridge,
instead of being calculated using the actual ingress RBridge.
