4.10 Configuring VRRP IPv6 Association
VRRP IPv6 association helps a VRRP IPv6 backup group rapidly perform a master/backup
VRRP switchover if a network link fails. This ensures proper service data forwarding.
4.10.1 Before You Start
Before configuring VRRP IPv6 association, familiarize yourself with the usage scenario,
complete the pre-configuration tasks, and obtain the data required for the configuration.
Applicable Environment
NOTE
The time after which a master/backup VRRP switchover is performed is three times the interval at which
VRRP Advertisement packets are sent.
VRRP IPv4 association can prevent traffic loss. If an object associated with a VRRP backup
group fails, the VRRP backup group is notified of the failure and performs a master/backup
VRRP switchover. Alternatively, if a master/backup VRRP switchover is performed, the VRRP
backup group instructs its associated object to perform a traffic switchover. The association
ensures proper traffic forwarding and improves link reliability.
VRRP6 means VRRP applications on IPv6 networks.
VRRP IPv6 association involves the following functions:
l
Association with interfaces: A VRRP IPv6 backup group tracks VRRP-disabled interfaces
connected to a network on the master device. If a VRRP-disabled interface fails, the VRRP
IPv6 backup group is notified of the fault and rapidly performs a master/backup VRRP
switchover.
l
Association with BFD sessions: A VRRP IPv6 backup group tracks BFD sessions. If a link
fails, a BFD session detects the fault, enters the Down state, and notifies the VRRP IPv6
backup group of the fault. After receiving the notification, the VRRP IPv6 backup group
rapidly performs a master/backup VRRP switchover.
Pre-configuration Tasks
Before configuring VRRP IPv6 association, complete the following tasks:
l
4.8 Configuring Basic Functions of a VRRP IPv6 Backup Group
l
Configure a common, link, or peer BFD session.
Data Preparation
To configure VRRP IPv6 association, you need the following data.
No.
