Configure VRRP on an AR router and connect the router to a firewall for external network access
The roadmap of configuring VRRP on an AR router and connecting the router to a firewall for external network access is as follows: 1. Configure VRRP on an AR router to implement two-node backup, and configure a virtual IP address. 2. Add the Layer 2 interface of a firewall on the intranet side to the same VLAN, and configure a VLANIF address. 3. Add the physical interface and VLANIF interface of the firewall to a security zone, and configure an inter-zone policy. 4. Configure the next hop for the route from the firewall to the intranet as a VRRP virtual IP address so that a normal link can be switched over to if an active link is interrupted. For details about the configuration, see the URL: Example for Connecting the AR to the Firewall Through VRRP.
