VRRP with Route and Interface Tracking In Figure 36-10, the VRRP priorities are configured so that Router A is the VRRP master, and Router B is the VRRP backup. Router A forwards IP traffic from clients to the external network through the VLAN 25 routing interface. The clients are configured to use the virtual IP address 192.168.10.15 as the default gateway. Figure 36-10. VRRP with Tracking Network Diagram External Network 192.168.200.0 VLAN 25 Router A Priority 200 VRID 10 192.168.10.15 Router B Priority 195 VLAN 10 192.168.10.1 VLAN 10 192.168.1.2 L2 Switch ` ` ` ` Default Gateway 192.168.10.15 Default Gateway 192.168.10.15 Default Gateway 192.168.10.15 Default Gateway 192.168.10.15 Without VRRP interface or route tracking, if something happened to VLAN 25 or the route to the external network, as long as Router A remains up, it will continue to be the VRRP master even though traffic from the clients does not have a path to the external network. However, if the interface and/or route tracking features are configured, Router A can decrease its priority value when the problems occur so that Router B becomes the master. 1040 Configuring VRRP
