Configuring Router Priority, Preemptive Mode And Tracking Function - HPE FlexNetwork HSR6800 series Configuration Manual

•
A VRRP group is removed after you remove all its virtual IP addresses, and all its configurations
become invalid.
•
Removal of the VRRP group on the IP address owner causes IP address collision. To avoid the
collision, change the IP address of the interface on the IP address owner before you remove the
VRRP group from the interface.
•
The virtual IP address of a VRRP group cannot be 0.0.0.0, 255.255.255.255, loopback
addresses, non-class A/B/C addresses or other illegal IP addresses such as 0.0.0.1.
Configuration prerequisites
Before creating a VRRP group and configuring a virtual IP address on an interface, configure an IP
address for the interface and make sure that it is in the same subnet as the virtual IP address.
Configuration procedure
To create a VRRP group and configure a virtual IP address:
Step
1. Enter system view.
2. Enter the specified interface
view.
3. Create a VRRP group and
configure a virtual IP address
for the VRRP group.

Configuration guidelines
•
The running priority of an IP address owner is always 255 and you do not need to configure it.
An IP address owner always operates in preemptive mode.
•
If you configure an interface to be tracked or a track entry to be monitored on a router that is the
IP address owner in a VRRP group, the configuration does not take effect. If the router is not the
IP address owner in the VRRP group later, the configuration takes effect.
•
The tracked interface can be a Layer 3 Ethernet interface, a VLAN interface, a Layer 3
aggregate interface, a synchronous/asynchronous serial interface, a POS interface, an
MP-group interface, an HDLC link bundle interface, or an RPR logical interface. The Layer 2
protocol used by the tracked synchronous/asynchronous serial interfaces can be PPP only, and
the tracked synchronous/asynchronous serial interfaces cannot be added to a virtual template
or MP-group.
•
If the state of a tracked interface changes from down or removed to up, the priority of the router
where the interface resides is automatically restored.
•
If the state of a track entry changes from negative or invalid to positive, the priority of the router
where the track entry is configured is automatically restored.
Configuration prerequisites
Before you configure router priority, preemptive mode and tracking function, create a VRRP group on
an interface and configure a virtual IP address for it.
Configuration procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, you can
determine which router in the VRRP group serves as the master.
To configure router priority, preemptive mode and the tracking function:
