Abstract

The present invention provides a method for realizing a virtual private local area network service based on BGP multi-homing connection in an operator's edge router of a DOCSIS / DPoE network, which includes the steps of: obtaining a cable modem configuration file from a background configuration server, wherein the The configuration file includes a BGP attribute subtype length value; configure the BGP signaling parameters of the multi-homing connection according to the BGP attribute subtype length value; create and maintain a pseudowire according to the BGP signaling parameters of the multi-homing connection, so as to communicate with the network Establish and maintain virtual private local area network services based on BGP multi-homing connections between other carrier edge routers. Wherein, the BGP attribute subtype length value includes: BGP multi-homing connection configuration subtype, which is used to configure specific parameter items in the BGP signaling parameters required to realize the virtual private local area network service based on BGP multi-homing connection. In addition, the present invention also proposes a method for automatically configuring route distinguishing parameters and route target parameters.

Description

technical field [0001] The present invention relates to the field of communication, in particular, the present invention relates to a method for realizing virtual private local area network service (VPLS) based on BGP multi-homing connection in an operator's edge router of a DOCSIS / DPoE network. Background technique [0002] Cable Lab (Cable TV Lab), DOCSIS (Cable Data Service Interface Specification) and DPoE (DOCSIS Configuration of EPON Specification) specifications support configuration on CMTS (Cable Modem Termination System) or DPoE system to support BGP-AD (border Gateway Protocol-Auto Discovery) LDP (Label Distribution Protocol) virtual private LAN service and BGP virtual private LAN service. In order to support these features, Wired Labs has defined the BGP Attribute Sub Type Length Value (BGP Attribute Sub TLV) (43.5.21) under the L2VPN Encoding TLV (43.5) to encode the Border Gateway Protocol signaling parameters required by RFC6074 or RFC4761 . [0003] However...
