Embodiment Construction

[0096] figure 1 A schematic diagram of a communication system of an embodiment provided for this application, such as figure 1 As shown, the communication system includes a first device and a second device. In the ORF protocol, the first device may receive a BGP update message from the second device, and the update message includes an ingress policy of the second device, and the ingress policy usually includes one or more virtual private network (virtual private network, VPN) Conditions for routing. The first device applies the condition to its own egress policy, and matches the locally stored VPN route according to the update message. If a VPN route is matched, the first device sends a BGP update message to the second device respectively, and each BGP update message may include one or more matched VPN routes; if there is no matched VPN route, no It is sent by the first device to the second device, so that when the first device sends routes to the second device, only the ma...

Abstract

The present application provides a communication method and a communication device. The method includes: the first device receives a first BGP update message from the second device, and the first BGP update message includes a routing target and a first address family identifier. The first device determines a first route associated with the routing target and the first address family identifier. The first device sends the first route to the second device, thereby realizing accurate sending of the route.

Description

technical field [0001] The present application relates to the technical field of communication, and in particular to a communication method and a communication device. Background technique [0002] With the gradual increase of network users and network routes, the pressure on sending equipment and receiving equipment will increase accordingly. In order to alleviate the pressure on the sending device and the receiving device, the standard RFC 4684 in the request for comments (request for comments, RFC) is generally used to define an outbound route filtering (Outbound Route Filtering, ORF) protocol. In the ORF protocol, the sending device can send the condition of the route it expects to receive to the receiving device through an update (update) message of Border Gateway Protocol (BGP), and the receiving device combines the information in the local routing table with the update message. Routes matching the conditions are sent to the sending device. [0003] However, the rece...
