Resilient interworking of shortest path bridging and Ethernet virtual private networks
Abstract:
An Ethernet network, an Ethernet method, and an Ethernet node provide active-active dual-homed interworking between two Ethernet networks. The network, method, and node can include two nodes interconnected each to a Shortest Path Bridging (SPB) network and an Ethernet Virtual Private Network (E-VPN). The two nodes can utilize a same Ethernet Segment Identifier (ESI) for the E-VPN network to cause the dual-homed links to appear as a single link from an E-VPN perspective and a dummy node to advertise an extra node in the SPB network enabling two paths therein.
