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 : Rbridges: Base Protocol Specification Author(s) : R. Perlman Filename : draft-ietf-trill-rbridge-protocol-07.txt Pages : 84 Date : 2008-2-25 RBridges allow for optimal pair-wise forwarding with zero configuration, safe forwarding even during periods of temporary loops, and multipathing for both unicast and multicast traffic. They achieve these goals using IS-IS routing and encapsulation of traffic with a header that includes a hop count. RBridges are compatible with previous IEEE 802.1 bridges as well as current IPv4 and IPv6 routers and end nodes. They are as invisible to current IP routers as bridges are and, like routers, they terminate the bridge spanning tree protocol. The design supports VLANs and optimization of the distribution of multi-destination frames based on VLAN and IP derived multicast groups. It also allows forwarding tables to be based on RBridge destinations (rather than end node destinations), which allows internal forwarding tables to be substantially smaller than in conventional bridge systems.
