VRRP configuration and multiple backup VRRP configuration instances

the VRRP group is disconnected, the status of the router will not change, or the Master, in this case, the host routing in this domain still follows this router, but the host in this domain cannot communicate with the outside world due to its disconnection of the uplink. Therefore, the uplink status detection is added to VRRP to solve this problem.Configure a VRRP

VRRP configuration based on Routing

VRRPEnsure that only one vro sends packets on behalf of the vro. The host sends data packets to the vro. The router that forwards the data packet is the master router. If the primary router cannot work for some reason at some time, the vro in the backup state will be selected to replace the original primary router. VRRP makes the host in the LAN seem to use only one vro, and maintains the connectivity of the route even if the first hop router fails.
