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

Configuring router priority, preemptive mode and tracking
function
Configuration prerequisites
Before you configure router priority, preemptive mode and tracking function, create a VRRP group
and configure its virtual IPv6 address.
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.
•
Interface tracking is not configurable on an IP address owner.
•
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 interfaces, 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 interfaces. 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
that owns the interface 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 procedure
By configuring router priority, preemptive mode, interface tracking, or a track entry, determine which
router in the VRRP group serves as the master.
To configure router priority, preemptive mode and interface tracking:
Step
1. Enter system view.
2. Enter the specified interface
view.
3. Configure the priority of the
router in the VRRP group.
4. Configure the router in the
VRRP group to operate in
preemptive mode and
configure preemption delay
of the VRRP group.
5. Configure the interface to be
tracked.
6. Configure VRRP to track a
specified track entry.
