Some embodiments of the invention provide a method for using route filtering to relay routes between members of hub router clusters in an SD-WAN to reduce redundant route notifications to route reflectors (RRs) that advertise routes to hub routers in multiple regions connected by the SD-WAN and multiple edge routers at sites across the multiple regions. The method is performed at a first hub router of a first cluster. From a first edge router at a first site in a first region, the method receives routes of the first edge router. The method distributes the routes of the first edge router to a particular RR directly connected to the first cluster. The method distributes, to each other hub router of the first cluster, the routes of the first edge router along with an identifier that indicates that the routes should not be redistributed to the particular RR.

This application discloses a communication method and a related apparatus, and relates to the field of communication technologies. The method is applied to a software defined wide area network (SD-WAN) overlay network. A customer premise equipment (CPE) autonomously generates an SD-WAN overlay routing table, so that communication reliability and flexibility are improved. A route reflector (RR) specifies an overlay multicast reverse path forwarding (RPF) route to the CPE to implement SD-WAN overlay multicast communication, and the CPE does not need to perform path computation autonomously, so that a computing power requirement of the CPE is reduced. An identifier of the CPE and an identifier of a site are carried in a multicast join message to implement the SD-WAN overlay multicast communication. A standard IP header is carried in a multicast service packet to implement the SD-WAN overlay multicast communication, so that generalization, applicability, and compatibility are improved.

The method involves receiving first routing information with the same destination address sent by at least two access devices to obtain a routing information set for the destination address; for each piece of first routing information in the routing information set, determining the first forwarding path corresponding to that first routing information; determining a target first routing information to be sent from the first routing information corresponding to the same first forwarding path; and sending the target first routing information corresponding to each first forwarding path to the routing end, so that the routing end can add it to the routing table for forwarding data traffic to the destination address. This application can achieve effective dissemination of routing information, thereby improving the forwarding quality of data traffic in a network communication system.

The invention discloses an over-limit routing processing method and device, computer equipment and a storage medium. The method belongs to the technical field of network control, and specifically comprises the following steps: after receiving a first route filtering message which is sent by a receiving device and is used for indicating filtering of an overrun route, determining a first route demand result of a first edge device in a first autonomous system for the overrun route; under the condition that the first route demand result represents that no demand exists, sending a second route filtering message for indicating to filter the ultralimit route to a second route reflector of the second autonomous system; wherein the second route filtering message is used for indicating the second route reflector to control the sending device to filter the overrun route.

Some embodiments of the invention provide a method for implementing an SD-WAN connecting multiple sites at multiple physical locations. The method is performed at a first hub router of the SD-WAN. The method establishes, with a first edge router of a first site in a first region, a new connection for the first hub router to use to connect the first edge router to a second edge router of a second site in the first region. The method determines that a peer-connection notification regarding the newly connected first edge router has to be sent to a first route reflector (RR) that does not connect directly with the first edge router but connects to routers in a second region. The method sends the peer-connection notification to the first RR to analyze and determine whether to obtain routes associated with the first edge router for advertising to routers in the second region.

The invention provides a cross-domain agent service discovery method based on BGP (Border Gateway Protocol) multi-protocol extension. The method comprises the following steps: a service discovery gateway of a first AS (Autonomous Community) generates a detail route containing instance information according to a registration request of an agent instance; the route reflector of the first AS aggregates the plurality of detailed routes to generate an aggregated route; the aggregation route comprises a gateway address of a first AS service discovery gateway; the route reflector of the first AS sends the aggregation route to other AS, so that other AS sends an instance information query request to a service discovery gateway of the first AS according to the agent service information; and the first AS returns instance information of the plurality of agent instances to the second AS according to the query request, so that a service consumer in the second AS calls the agent instances in the first AS according to the instance information. According to the method, routing information containing agent service information is spread among different autonomous systems by expanding the BGP, and cross-domain agent service discovery is achieved.
