The embodiment of the invention provides a method and equipment for connection establishment and relates to the field of communication. The invention solves the problem of network connection interruption caused by the failure of a heartbeat line. The method comprises the following steps that after upstream primary network equipment detects that a link between a first heartbeat line port of the upstream primary network equipment and a second heartbeat line port of upstream standby network equipment is disconnected, downstream network equipment receives a first status notification message sent by the upstream primary network equipment through a primary port and switches a slave port of the downstream network equipment from a Standby status to a Forwarding status according to the first status notification message, so that the upstream primary network equipment is connected with the upstream standby network equipment through the primary port and the slave port of the downstream network equipment, wherein both the main port and the slave port are in Forwarding statuses. Through the method and the equipment provided by the embodiment of the invention, the upstream primary network equipment is connected with the upstream standby network equipment.
Description
technical field [0001] The present invention relates to the communication field, in particular to a connection establishment method and device. Background technique [0002] Smart Link, also known as a backup link, is a solution that provides a reliable and efficient backup and switching mechanism for dual uplink links, and is often used in dual uplink networking. [0003] A Smart Link group contains two ports on the same access device, one of which is the master port and the other is the slave port. The master port is in the forwarding state, and the slave port is blocked and in the standby state. When the link of the primary port in the forwarding state fails (such as a physical failure or an OAM connection failure, etc.), the Smart Link group will automatically block the primary port and switch the secondary port from the standby state to the forwarding state. [0004] VRRP (Virtual Router Redundancy Protocol, Virtual Router Redundancy Protocol) is currently the most wi...
