Abstract
Systems and methods are disclosed for processing framed routes initiated by user equipment (UE) at customer-premises equipment (CPE) and gateways using protocol configuration options (PCO). The PCO can include encoding and decoding framed route information using a PCO information element (IE). The framed route information can include a framed route and a virtual private networking routing and forwarding (VRF) name. The framed route information can also include a tunnel identifier and a packet data protocol (PDP) address. The gateway can include a packet data network gateway (PGW) and a gateway general packet radio service support node (GGSN). When the gateway receives an attach request message from the UE with the encoded PCO, the gateway decodes the PCO to extract the framed route and VRF name, associates a tunnel identifier and PDP address with the extracted framed route and VRF name, and installs the framed route in a corresponding VRF.
