Information About Ethernet Over GRE
Ethernet over GRE (EoGRE) 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
are terminated on a service provider broadband network gateway, the end host’s traffic is terminated and
subscriber sessions are initiated for the end host.
The following figure shows the structure of the Ethernet over GRE.
