Configuring Vrrp Packet Attributes - H3C S9500E Series Configuration Manual

decrease by a specified value; when the state of the track entry becomes positive or invalid, the
weight values of all VFs on the routers restore their original values.
To configure VF tracking:
To do...
1. Enter system view
2. Enter the specified interface
view
3. Configure the VF to monitor a
specified track entry
You can configure the VF tracking function when VRRP works in either the standard protocol mode or
•
load balancing mode; however, the VF tracking function is effective only when VRRP works in load
balancing mode.
Do not configure VF tracking on an IP address owner.
•
By default, the weight of a VF is 255, and its lower limit of failure is 10.
•
If the weight of a VF is higher than or equal to the lower limit of failure, the priority of the VF is always
•
255 and does not change with the weight value. Therefore, in case of an uplink failure, only when the
weight of the VF owner decreases a properly specified value and becomes lower than the lower limit of
failure, can another VF takes over the VF owner's work and becomes the AVF.

Configuring VRRP packet attributes

Configuration prerequisites
Before configuring the relevant attributes of VRRP packets, you should first create a VRRP group
and configure a virtual IP address for it.
Configuration procedure
To configure VRRP packet attributes:
To do...
1. Enter system view
2. Enter the specified interface
view
3. Configure the authentication
mode and authentication key
when the VRRP groups send
and receive VRRP packets
Use the command...
system-view

number
vrrp vrid virtual-router-id weight
