About This Chapter
A VRRPor VRRP6 backup group allows a backup to take over network traffic from a master
if the master fails.
7.1 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.
7.2 VRRP Features Supported by the S3700
VRRP features include the VRRP backup group in master/backup mode, VRRP backup group
in load balancing mode, tracking of the interface status, fast VRRP switchover, ping of the virtual
IP address, VRRP security authentication, smooth VRRP switching, and Management Virtual
Router Redundancy Protocol (mVRRP).
7.3 Configuring the VRRP Backup Group
By configuring the VRRP backup group in master/backup mode or load balancing mode, you
can implement the communication between hosts inside a LAN and external networks.
7.4 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.
7.5 Configuring VRRP to Tracking the BFD Session Status
This section describes how to configure VRRP to track the BFD session status to implement fast
switchover.
7.6 Configuring VRRP Security
On a network at security risks, by configuring an authentication mode of VRRP packets, you
can protect devices against attacks.
7.7 Adjusting and Optimizing VRRP
By adjusting parameters of a VRRP backup group, you can optimize the functions of the VRRP
backup group.
7.8 Configuring mVRRP Backup Groups
An mVRRP backup group can be bound to other member backup groups and determine the
status of member backup groups according to the bindings. This is applicable to the scenario
where a device is dual-homed to master and slave devices on a MAN.
