A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transparent Interconnection of Lots of Links Working Group of the IETF. Title : Centralized Replication for BUM traffic in active-active edge connection Authors : Weiguo Hao Yizhou Li Muhammad Durrani Sujay Gupta Andrew Qu Tao Han Filename : draft-ietf-trill-centralized-replication-01.txt Pages : 14 Date : 2015-02-09 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.
