Router configuration VRRP multiple backup groups and implementation of VRRP load Balancing mode

VRRP technology is a technology that solves the problem of single point fault in the host configuration single gateway in the network, by configuring multiple routers into a VRRP group, each VRRP group fictitious a virtual router as the gateway of the host in the network. In a VRRP group, all the real routers elect a top-level router as the primary router. The forwarding of a virtual router is assumed by the primary router.

When you build a remote network connection, if you configure a VRRP backup, it can cause the backup line to be idle, wasteful, and one that allows you to consider using VRRP multiple-group backups, two links to each other, and forwarding data at the same time.
