Abstract

The present disclosure relates to a route publishing method and device. The method includes: obtaining the extended community attribute RT information of each PE device from each service provider network edge PE device connected to the RR, and the RT information includes the inbound extended community attribute IRT Extending the community attribute ERT in the outbound direction; and sending a target IRT matching the ERT to the PE device corresponding to the ERT, so that the PE device corresponding to the ERT determines a route to be advertised according to the target IRT. Therefore, the PE device corresponding to the ERT can determine the route to be advertised according to the target IRT, that is, the PE device corresponding to the ERT automatically uses the target IRT as the RT filtering policy. Manual configuration of RT filtering policy on the terminal PE device, the disclosure automatically sets the RT filtering policy without manually configuring the RT filtering policy, flexible operation, and good user experience.

Description

technical field [0001] The present disclosure relates to the technical field of communication, and in particular, to a route publishing method and device. Background technique [0002] MPLS (Multi-Protocol Label Switching, multi-protocol label switching) L3VPN (Layer3Virtual Private Network, three-tier virtual private network) is a PE (Provider Edge, service provider network edge) equipment L3VPN technology, which uses BGP (Border Gateway Protocol, border gateway protocol) RT (Route Target, extended community attribute) to control the publication of VPN routes. [0003] The VPN instance on the PE device has two types of RT attributes: ERT (Export Route Target, outbound extended community attribute) and IRT (Import Route Target, inbound extended community attribute). Among them, after the local PE device learns the IPv4 route from the Site (site) connected to itself, it converts the IPv4 route into a VPN-IPv4 route, sets ERT for the VPN-IPv4 route, and publishes the VPN-IPv4...
