About This Chapter
A VRRP backup group allows a backup to take over network traffic from a master if the master
fails.
4.1 VRRP Introduction
VRRP, a fault-tolerant technology, implements routing among multiple egress gateways by
separating physical devices from logical devices.
4.2 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.
4.3 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.
4.4 Configuring a Fast VRRP Switchover (in Common Mode)
By tracking the BFD session status or the EFM OAM session status, a VRRP backup group
implements VRRP switchovers rapidly.
4.5 Configuring VRRP Fast Switchover (Using BFD Sampling)
By configuring a BFD session in BFD sampling mode, you can address the problem that a link
BFD session fails to be set up between an NPE and a PE.
4.6 Configuring Ignorance of the Down of an Interface Where the mVRRP Backup Group Is
Configured
By configuring mVRRP with the function of ignoring the interface Down event, you can resolve
the problem that mVRRP and a peer BFD session cannot be configured between NPEs.
4.7 Configuring VRRP Applications in VLANIF
By configuring a VRRP backup group on VLANIF interfaces, you can perform the fast VRRP
switchover.
4.8 Configuring VRRP Security
On a network at security risks, by configuring an authentication mode of VRRP packets, you
can protect devices against attacks.
4.9 Configuring VRRP Smooth Switching
