Abstract: A packet processing method, a device, and a system are disclosed. In the method, a first provider edge (PE) device receives a first virtual extensible local area network (VXLAN) packet through a first point-to-point (P2P) VXLAN tunnel between the first PE device and a third PE device A customer edge (CE) device is dual-homed to the first PE device and a second PE device respectively through a first Ethernet link and a second Ethernet link. The first PE device forwards the first VXLAN packet to the second PE device through a third P2P VXLAN tunnel from the first PE device to the second PE device when there is a fault on the first Ethernet link. The first Ethernet link connected to the first PE device and a link formed by the third P2P VXLAN tunnel and the second Ethernet link have a primary/secondary relationship.

Abstract: This application provides a VXLAN packet processing method, a device, and a system. After determining that a data packet sent by a CE device is a BUM packet, a PE device encapsulates the BUM packet to generate a VXLAN packet including an ESI label and a VXLAN packet including a BUM traffic label. The VXLAN packet including the ESI label is sent to an active-active gateway, so that the gateway can block forwarding of traffic to the CE device by using an interface configured with an ESI, to avoid a loop between the PE device and the CE device. The VXLAN packet including the BUM traffic label is sent to a remote PE, to block forwarding of the VXLAN packet to the CE device by using a secondary DF interface, thereby avoiding a multi-packet problem.

Abstract: A packet processing method, a device, and a packet processing system are provided. The method includes: generating, by a VTEP device at one end of a VXLAN tunnel, a PPP over VXLAN packet that carries control information, and transmitting the PPP over VXLAN packet to a VTEP device at the other end of the VXLAN tunnel by using the VXLAN tunnel. The VTEP device at the other end of the VXLAN tunnel may perform, based on the control information in the PPP over VXLAN packet, a function defined in PPP. In this way, a VXLAN control plane is implemented by using the PPP, and overheads and complexity of implementing the VXLAN control plane are reduced.
