Embodiment Construction

[0052] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0053] figure 1 Shown is a schematic diagram of the implementation principle of a host connected to the active and standby gateways through a switch, and a local area network connected through the active and standby gateways.

[0054] The gateways that the user-side host accesses through the access switch (SWITCH) are ROUTER1 and ROUTER2 respectively. The user deploys a VRRP instance on the interfaces connecting ROUTER1 and ROUTER2 to SWITCH respectively. ROUTER1 and ROUTER2 form a VRRP group as the user-side gateway, and the IP address of the virtual gateway is 1.1.1.10. The interfaces connecting ROUTER1, ROUTER2, and SWITCH join the same Layer 2 domain network, and the Layer 2 domain network is identified as VLAN 10.

[0055] Set the priority of the VRRP instance of ROUT...

Abstract

The invention discloses a gateway deployment method and a gateway deployment device, aiming to solve the problem that services are limited due to the fact that an existing VRRP (virtual router redundancy protocol) router fails to achieve cross-region deployment. The gateway deployment method includes establishing a first VXLAN (virtual extensible local area network) tunnel with a first gateway and a second gateway which are deployed in different regions; receiving a VRRP message transmitted by the second gateway through the first VXLAN tunnel; recognizing a priority of VRRP instances configured on the second gateway based on the VRRP message; determining a primary gateway and a spare gateway in the first gateway and the second gateway based on a priority of VRRP instances configured on the first gateway and the priority of the VRRP instances configured on the second gateway. The gateway deployment method determines the primary gateway and the spare gateway by deploying the VXLAN tunnel in between and can enable the VRRP message to be transmitted through the VXLAN tunnel, so that the primary gateway and the spare gateway of a VRRP gateway are deployed more flexibly and conveniently.

Description

technical field [0001] The present application relates to the communication field, and in particular to a gateway deployment method and device. Background technique [0002] Usually the default next-hop address of the host is the router as the gateway, and the host usually configures a static route to obtain the gateway address, which increases the possibility of a single point of failure. When the gateway is unavailable, it will bring disastrous results, because when In the event of a gateway failure, all connected hosts will experience a network outage because they cannot detect other available alternative paths. [0003] Virtual Router Redundancy Protocol (VRRP) is an election protocol. Each VRRP router running VRRP protocol can dynamically elect a router from multiple VRRP routers in the LAN according to the priority of each VRRP router. The main gateway is used to undertake the work of the virtual gateway, the main gateway controls the Internet Protocol (Internet Proto...
