2BConfiguring VRRP

The interfaces that VRRP involves can be only Layer 3 Ethernet interfaces and subinterfaces, VLAN

interfaces, and Layer 3 aggregate interfaces unless otherwise specified.

VRRP cannot be configured on an interface of an aggregation group.

The term "router" in this document refers to both routers and routing-capable firewalls and UTM devices.

VRRP overview

As shown in 475HFigure 1, you can typically configure a default route with the gateway as the next hop for

every host on a LAN. All packets destined to other network segments are sent over the default route to the

gateway, which then forwards the packets. However, when the gateway fails, all the hosts that use the

gateway as the default next-hop router fail to communicate with external networks.
