Abstract:
In TRILL active-active access, an RPF (Reverse Path Forwarding) 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 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. This document updates RFC 6325.
