Title: VXLAN PACKET PROCESSING METHOD, DEVICE AND SYSTEM
Abstract:
Provided in the present invention are a VXLAN packet processing method, device and system. After a PE device determines that a data packet sent by a CE device is a BUM packet, the BUM packet is encapsulated to generate a VXLAN packet comprising an ESI label and a VXLAN packet comprising a BUM traffic label. The VXLAN packet which comprises an ESI label is sent to an active-active gateway, so that the gateway can block an interface configured as an ESI from forwarding traffic to the CE device, avoiding the occurrence of a loop between the PE device and the CE device. The VXLAN packet which comprises a BUM traffic label is sent to a distal PE, so as to block the interface of the DF device from forwarding the VXLAN packet to the CE device, avoiding a multi-packet problem. The present application improves the gateway reliability of the EVPN VXLAN.
