Abstract

The invention relates to an intercommunication method and device for VXLAN (Virtual eXtensible Local Area Network) EVPN (Ethernet Virtual Private Network) symmetric networking. The method comprises the following steps: configuring a public three-layer virtual network identifier VNI on a VXLAN interface of VTEP equipment; after the local end VTEP device receives the target traffic, routing query is carried out on a destination address corresponding to the target traffic; when the destination address hits the gateway direct connection route and the corresponding address resolution information is not obtained, generating a detection route; the detection route is sent to an opposite end VTEP device; receiving an EVPN (Ethernet Virtual Private Network) second-class route sent by the opposite end VTEP equipment; and forwarding the target traffic according to the EVPN second-class route so as to realize intercommunication under the VXLAN EVPN symmetric networking. According to the intercommunication method and device for the VXLAN EVPN symmetric networking, the intercommunication obstacle caused by the loss of the address resolution information in the one-way traffic scene can be solved, and the rapid establishment and reliable intercommunication of the two-way traffic are realized.
