Abstract

The invention provides a routing configuration method and device, applied to a controller in an SDN. The method comprises the following steps: RT attributes of a VPN example of a tenant and a routing strategy of a VPN example of an external network are configured through the controller, so that gateway equipment sets RT attributes for routing from different external network equipment according to the routing strategy, matches the RT attributes of the routing with the RT attributes of the VPN example of the tenant, adds the routing into the VPN example of the tenant after successfully matching, and guides the flow of the tenant to be forwarded to the external network. By means of the routing configuration method and device, dynamic updating of the routing on the gateway equipment can be realized.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a routing configuration method and device. Background technique [0002] SDN (Software Defined Network, Software Defined Network) is a new innovative network architecture, which realizes flexible control of network traffic by separating the control plane and data plane. [0003] Existing SDN network cloud egress is usually concentrated on a cloud gateway, outbound network traffic passes through the default gateway, and static routing points to the IP (Internet Protocol, IP for short) of the external network device. [0004] Generally speaking, traffic sent by tenants to the external network is forwarded to the external network by matching the static route on the gateway device. Since devices other than the cloud gateway are uncontrollable, if the next hop of the static route is unreachable, traffic cannot be forwarded to the external network. Contents of ...
