Prerequisites for Configuring Ethernet Over GRE
Before you configure the Ethernet over GRE feature on the Cisco ASR 1000 Series Aggregation Services
Routers, ensure that the following prerequisites are met:

Information About Configuring Ethernet Over GRE
The Cisco ASR 1000 Series Aggregation Services Routers serve as a service provider broadband network
gateway that:
• Terminates IPv4 or IPv6 GRE tunnels.
• Manages the subscriber session for end-host clients.
The EoGRE feature works with legacy residential gateways and CPE devices to terminate the Ethernet L2
traffic in the Cisco ASR 1000 Series Aggregation Services Routers. When configured as an intelligent Wireless
Access Gateway (iWAG) with EoGRE access tunneling support, the Cisco ASR 1000 Series Aggregation
Services Routers can extend mobility and the ISG services in support of these legacy devices.
