step S32, if it is detected that the virtual route has an update operation, a route update interface is invoked to obtain private network route information.
In this embodiment, after receiving a setting request for setting a private network route through an operation management interface, the NAT plug-in starts a thread again, detects whether an update operation exists on the Virtual route, and if it is detected that the update operation related to the Virtual route exists, calls an update router (update route) interface to obtain private network route information from an MQ, and automatically logs in the gateway device through the NAT plug-in again to configure and issue a private network route policy to the gateway device under the same VRF (Virtual Routing Forwarding table).
After step S30, the method further includes:
and step S40, acquiring routing flow tables of the public network and the private network, and issuing the routing flow tables to the gateway equipment through the SDN controller so that the gateway equipment can select a routing line to enter the public network or the private network according to the routing flow tables.
