Industry Cellular Gateway
As shown in the diagram, Master Gateway and Backup
Gateway are redundant gateway group of Network-A.
Subnet of network-A is 10.0.75.0/24. Master gateway
has LAN
IP 10.0.75.1 and WAN IP 203.95.80.22.
Backup gateway has LAN IP 10.0.75.2 and 118.18.81.33
for WAN-1. They both serve as NAT routers.
Specify the ID of VRRP virtual server to be "253" and its
IP address to be "10.0.75.200". The priority of the
master gateway is 254 and it is larger than the one (253)
of the backup gateway. At first stage, all data from the
Intranet go through the master gateway that has the
highest priority. Once the master Internet connection is
broken, the backup gateway will take over the data
transmitting job and serve as the master gateway.
When a gateway with higher priority recovers from
broken connection, it will take over data transmitting
again.
