Cisco® Ethernet over GRE (EoGRE) is a tunneling protocol that enables tunneling of Layer 2 packets encapsulated in a Generic Routing Encapsulation (GRE) header over IP core networks. It is a new aggregation solution for aggregating WiFi traffic from hotspots. This solution enables customer premises equipment (CPE) devices to bridge the Ethernet traffic coming from an end host and encapsulate the traffic in Ethernet packets over an IP GRE tunnel. When the IP GRE tunnels terminate on a service provider broadband network gateway, the end host’s traffic also terminates, and the end host initiates subscriber sessions. This demonstration uses Cisco Virtual Internet Routing Lab (VIRL). VIRL is a multi-purpose network virtualization platform that provides an easy way to build, configure, and test new or existing network topologies with an intuitive user interface (UI).
