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.
