Abstract: Embodiments of this application disclose a configuration method and a controller. The configuration method is applied to a network on which detection is performed by using the TWAMP, and may include: receiving, by a controller, a request packet sent by an ingress network device, where the ingress network device is a network device through which a service flow flows into the network, and the request packet includes a destination IP address of the service flow; and determining, by the controller, based on the destination IP address, that the service flow is an X2 service flow, and sending configuration information for TWAMP detection to the ingress network device and an egress network device, where the egress network device is a network device through which the service flow flows out of the network.

Abstract: A method for preventing a network attack, including: receiving, by a first network node in a Ethernet virtual private network (EVPN), a first packet, where the first packet carries a first media access control (MAC) address, and the first MAC address is a source MAC address of the first packet; and determining first MAC entry information, where the first MAC entry information includes a correspondence between the first MAC address, an identifier of the first MAC address, and egress port information of the first MAC address, and the identifier of the first MAC address is used to indicate that an egress port corresponding to the first MAC address is a trusted port. This method can reduce a risk that the EVPN breaks down caused by attacking the EVPN by an attacker.
