Embodiment Construction

[0035] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described below are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0036] figure 1 is a flow chart of a method for publishing network routes provided by an embodiment of the present invention, such as figure 1 shown, including:

[0037] Step S101: starting from the local route import node in the network, traversing along the preset network topology according to the maximum number of hops, and obtaining a traversal result list including the traversed listener nodes and reflector nodes;

[0038] Step S102: Generate a network-side route according to the traversal result list, and publish the generated network-side route to corresponding nodes in the network.

[0039] Wherein, the network topology includes multiple nodes; ...

Abstract

The invention discloses a method and device for publishing a network static route, which relates to the technical field of data communication. The method comprises: starting from a local route introduction node in the network, and proceeding along a preset network topology according to the maximum number of hops Traversing to obtain a traversal result list including the traversed listener nodes and reflector nodes; generating a network-side route according to the traversal result list, and publishing the generated network-side route to corresponding nodes in the network. The present invention customizes the publishing rules through metadata configuration to more flexibly and quickly adapt to the L3VPN route publishing algorithm of various networking scenarios.

Description

technical field [0001] The invention relates to the technical field of data communication, in particular to a method and device for publishing network routes. Background technique [0002] Nowadays, the method for realizing L3VPN (L3Virtual Private Network, three-layer virtual private network) route publication is the MP-BGP (Multiprotocol-Border Gateway Protocol, multi-protocol-Border Gateway Protocol) protocol in the router field, which is a distributed The release method of the architecture, by configuring the neighbor relationship between PE (Provider Edge, Provider Edge Device) nodes, enables each PE node to learn from IGP (Interior Gateway Protocol, Interior Gateway Protocol) or through statically configured local routes. other PE nodes. Since the configuration of the neighbor relationship is shared between each L3VPN instance, in order to control whether each L3VPN instance advertises a route between a pair of neighbor relationships, RT (Route Target) technology is i...
