Abstract
A packet processing method, and a device and a system includes receiving, by a provider edge (PE) device, a first virtual extensible local area network (VxLAN) encapsulated packet sent by a network virtualization edge (NVE) device, where the PE device and the NVE device are located in a same data center (DC), and the first VxLAN encapsulated packet includes a first VxLAN network identifier (VNI); parsing, by the PE device, the first VxLAN encapsulated packet to obtain the first VNI; obtaining, according to a correspondence between a VNI and a virtual routing and forwarding (VRF) table, a first VRF table that corresponds to the first VNI; searching, by the PE device, the first VRF table for a route according to a destination Internet Protocol (IP) address of the first VxLAN encapsulated packet; and forwarding the first VxLAN encapsulated packet.
