Abstract
A method that improves multi-area routed Ethernet network design, in which multipath implementation in each of the areas is independent of each other area to allow optimal network design in each area. The network implements a shortest path bridging medium access control (SPBM) protocol. The areas include a Level 2 (L2) routing area coupled to a Level 1 (L1) routing area via multiple area border bridges (ABBs). The L1 routing area including a backbone edge bridge (BEB) coupled to the ABBs via multiple L1 multipath instances identified by respective backbone VLAN identifiers (B-VIDs). The ABBs receive an advertisement from the BEB that indicates a set of BEB identifiers, each of which identifies the BEB and is associated with a respective B-VID. Each of the BEB identifiers is unique. The ABBs also advertise into the L2 routing area, and translate the B-VIDs based on service identifiers for frames transiting the ABBs.
