Abstract
Embodiments of the present invention provide a network label allocation method, a device, and a system, which enable a local PE to distinguish packets from different remote PEs. The method includes: generating, by a local provider edge PE, a VPN label route for each remote PE, where VPN labels in VPN label routes of different remote PEs are different, and the remote PE and the local PE at least belong to a same VPN; and sending the VPN label route to the remote PE, so that the remote PE separately matches an IP address of the remote PE with a target device IP address in the VPN label route, and matches an import route target RT of each VRF of the remote PE with a route target RT in the VPN label route, a packet related to a successfully matched VRF.
