Abstract

The present invention provides a method and device for realizing remote multi-homing networking. The method includes: associating the first Leaf device with the second remote Leaf device, and the first Leaf device determines the master Leaf device and the second Leaf device from the second Leaf device. Prepare the Leaf device, and notify the second Leaf device of the identity confirmation parameters, so that the second Leaf device determines the identity type of the second Leaf device associated with the first Leaf device, thereby realizing the remote multi-homing access of the first Leaf device, Improve access reliability.

Description

technical field [0001] The present invention relates to the technical field of network communication, in particular to a method and device for realizing remote multi-homing networking. Background technique [0002] EVPN (Ethernet Virtual Private Network) is a Layer 2 VPN technology. The control plane uses MP-BGP (Multiprotocol-Border Gateway Protocol) to advertise EVPN routing information, and the data plane uses VXLAN ( Virtual eXtensible LAN, extensible virtual local area network) encapsulation to forward packets. EVPN can provide Layer 2 interconnection for the same subnet of the same tenant based on the existing service provider or enterprise IP (Internet Protocol) network, and provide Layer 3 interconnection for different subnets of the same tenant through the EVPN gateway, and provide It provides Layer 3 interconnection with external networks. Currently, the EVPN network does not support the remote multi-homing networking of leaf (branch) devices. Contents of the i...
