TRAFFIC CONTROL METHOD AND RELATED DEVICE

Embodiments of this application disclose a traffic control method and a related device. A control management device advertises a VPN route to a PE device based on a VPNv4 address family, a VPNv6 address family, or an L3EVPN address family, where the VPN route includes an IP address prefix of a destination host and a network address of a next hop to the IP address prefix, and the network address of the next hop is a private IP address. The PE device generates, based on the VPN route, a VRF entry including the IP address prefix and outbound interface information, where the outbound interface information identifies an outbound interface that is of the PE device and that is connected to the next hop. In this way, the VPN route is iterated to a next hop of a private network, and the control management device sends the VPN route to the PE device in a lightweight and flexible manner, so that the PE device supports a function of private network redirection forwarding in a plurality of different network scenarios.
