Step Command Remarks
1. Enter system view. system-view N/A
2. Enter the specified interface
view.
interface interface-type
interface-number
N/A
3. Configure the VF to monitor a
specified track entry and
specify the amount by which
the weight decreases.
vrrp ipv6 vrid virtual-router-id
weight track track-entry-number
[ reduced weight-reduced ]
No track entry is specified by
default.
NOTE:
•
You can configure the VF tracking function when VRRP works in either standard protocol mode or load
balancing mode; however, the VF tracking function is effective only when VRRP works in load balancing
mode.
• By default, the weight of a VF is 255, and its lower limit of failure is 10.
• If the weight of a VF owner is higher than or equal to the lower limit of failure, the priority of the VF
owner is always 255 and does not change with the weight value. Therefore, if an uplink fails, another VF
takes over the VF owner's work and becomes the AVF only when the weight of the VF owner decreases
by a properly specified value and becomes lower than the lower limit of failure. In other words, the
weight of the VF owner decreases by more than 245.
Configuring VRRP packet attributes
Configuration prerequisites
Before you configure the relevant attributes of VRRP packets, create a VRRP group and configure a virtual
IPv6 address.
Configuration procedure
To configure VRRP packet attributes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter the specified interface
view. interface interface-type
interface-number
N/A
3. Configure the authentication
mode and authentication key
when the VRRP groups send
or receive VRRP packets.
vrrp ipv6 vrid virtual-router-id
authentication-mode simple key
Optional.
Authentication is not performed by
default.
4. Configure the time interval for
the master in the VRRP group
to send VRRP advertisement.
vrrp ipv6 vrid virtual-router-id timer
advertise adver-interval Optional.
100 centiseconds by default.
