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.
