Abstract

The invention discloses a processing method of a designated forwarder (DF), a controller, and a provider edge device, which are used to realize centralized control on DF election so as to effectively realize unified management of DF election. The processing method of a designated forwarder provided by one embodiment of the invention comprises the following steps: a controller receives DF request information sent by multiple provider edge (PE) devices in the same core network; the controller selects one PE device as a PF from the multiple PE devices according to the DF request information sent by each of the multiple PE devices, and gets DF election information; and the controller sends the DF election information to each of the multiple PE devices.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a designated forwarder (full English name: Designated Forwarder, English abbreviation: DF) processing method, controller and provider edge (English full name: Provider Edge, English abbreviation: PE) equipment. Background technique [0002] Ethernet Virtual Private Network (full English name: Ethernet Virtual Private Network, English abbreviation: EVPN) is a Layer 2 VPN technology, and the basic protocol is defined in RFC7432. The PE device can learn the MAC of the locally accessed customer edge (full English name: Customer Edge, English abbreviation: CE) device through the media access control (English full name: Media Access Control, English abbreviation: MAC) learning method at the data level. Then the PE devices spread and synchronize the locally learned MAC through the Border Gateway Protocol (English full name: Border Gateway Protocol, English abbreviation: BGP). ...
