Claim 0:
1. A traffic control method, comprising:
obtaining, by a network device, a configuration policy from a management device, wherein the configuration policy is associated with controlling access between a plurality of branch devices, and wherein each of the plurality of branch devices is connected to the network device;
configuring, by the network device, a destination for all traffic being sent between the plurality of branch devices based on the configuration policy, wherein:
the configuring of the destination for all the traffic being sent between the plurality of branch devices causes the traffic to be transmitted to the destination and prevents access between each branch device of the plurality of branch devices and each other branch device, and
the destination is a filtering device on the network device;

receiving, by the network device, access traffic from a target branch device, wherein the target branch device is one of the plurality of branch devices;
redirecting, by the network device, all of the access traffic of the target branch device to the filtering device;
obtaining, by the network device, filtered traffic from the filtering device, wherein the filtered traffic is traffic obtained after the filtering device filters the access traffic of the target branch device; and
sending, by the network device, the filtered traffic to a local area network (LAN) device.
