About This Chapter
A VRRP backup group allows a backup to take over network traffic from a master if the master
fails.
2.1 VRRP Overview
The Virtual Router Redundancy Protocol (VRRP) groups multiple routers into one virtual router,
and sets the default gateway address as the IP address of the virtual router.
2.2 VRRP Features Supported by the AR2200-S
VRRP features include the VRRP backup group in master/backup mode, VRRP backup group
in load balancing mode, interface status tracking, virtual IP address ping, and VRRP security
authentication.
2.3 Configuring a VRRP Backup Group
By configuring a VRRP backup group in master/backup mode or load balancing mode, you can
implement communication between hosts inside a LAN and on external networks.
2.4 Configuring VRRP to Track the Status of an Interface
By configuring a VRRP backup group to track the interface status, you can implement the backup
function when the interface fails.
2.5 Configuring VRRP Applications in VLANIF
By configuring a VRRP backup group on VLANIF interfaces, you can perform the fast VRRP
switchover.
2.6 Configuring VRRP Security
On a network at security risks, by configuring an authentication mode of VRRP packets, you
can protect devices against attacks.
2.7 Adjusting and Optimizing VRRP
By adjusting parameters of a VRRP backup group, you can optimize the functions of the VRRP
backup group.
2.8 Configuring VRRP Version Upgrade
Upgrade the VRRP version from version 2 to version 3.
