Abstract:
1. An Ethernet network, comprising: a first Ethernet node connected to both a first Ethernet network operating a first protocol and a second Ethernet network operating a second protocol; a second Ethernet node connected to both the first Ethernet network and the second Ethernet network, wherein the first Ethernet node and the second Ethernet node are collectively in an active-active interworking configuration therebetween; and a dummy node associated with the first Ethernet node to represent connectivity to the first Ethernet network within the second protocol; wherein the active-active interworking configuration comprises using a same link number for the first protocol for the first Ethernet node and the second Ethernet node and using the dummy node to advertise an extra node in the second protocol enabling two paths in the second protocol; wherein the first protocol comprises Ethernet Virtual Private Network (E-VPN) and the second protocol comprises Shortest Path Bridging Media Access Control (SPBM); and wherein the same link number comprises a same Ethernet Segment Identifier (ESI) such that, from the E-VPN perspective, the first Ethernet node and the second Ethernet node appear to support an SPBM network using a single link.
