Abstract

The embodiment of the present invention discloses a route insertion method and device, the method comprising: receiving the private network route sent by the CE device at the edge of the user network; extending the community attribute according to the outbound direction of the virtual private network VPN instance bound to the CE device ERT and the private network route generate a VPN route; traverse the pre-stored pluggable VPN instance list of the bound VPN instance, and insert the VPN route into each pluggable VPN instance included in the pluggable VPN instance list, wherein The inbound extended community attribute IRT of the pluggable VPN instance contained in the pluggable VPN instance list matches the ERT of the bound VPN instance, and the embodiment of the present invention is applied to reduce the number of insertion judgments when the route is inserted into the VPN instance, thereby improving The processing performance of border gateway protocol BGP system for route insertion.

Description

technical field [0001] The invention relates to the technical field of information communication, in particular to a method and device for routing insertion. Background technique [0002] In the BGP (Border Gateway Protocol, Border Gateway Protocol) system, the CE (Customer Edge, user network edge) routing device enters the private network route to the PE (Provider Edge, service provider network edge) routing device, and the PE device sends the Insert the private network route into the routing table of the VPN (Virtual Private Network, virtual private network) instance bound to the CE device, and generate an RT (Route Target, extended community attribute) and the ERT ( Export Route Target, outbound extended community attribute) the same VPN route, the VPN route can be a VPNv4 route or a VPNv6 route. After generating the VPN route, the PE device needs to traverse all other VPN instances in the PE device except the bound VPN instance, and insert the generated VPN route into t...
