Configuring Router Priority, Preemptive Mode And Tracking Function - HP A5830 series Configuration Manual

To do...
• Configure the VRRP group
with a virtual IPv6 address,
which is a global unicast
address
When a router is the IP address owner in a VRRP group, HP recommends you not to use the IPv6
address of the interface (virtual IPv6 address of the VRRP group) to establish an OSPFv3 neighbor
relationship with the adjacent router, that is, not to use the ospfv3 area command to enable OSPFv3 on
the interface. For more information about ospfv3 area command, see Layer 3—IP Routing Command
Reference.
A VRRP group is removed after you remove all virtual IPv6 addresses in it. In addition, configurations on
that VRRP group do not take effect any longer.
Removal of the VRRP group on the IP address owner causes IP address collision. To resolve the collision,
change the IPv6 address of the interface on the IP address owner first and then remove the VRRP group
from the interface.
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 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:
To do...
• Enter system view
•
Enter the specified interface
view
•
Configure the priority of the
router in the VRRP group
• Configure the router in the
VRRP group to work in
preemptive mode and
configure preemption delay of
the VRRP group
• Configure the interface to be
tracked
Use the command...
vrrp ipv6 vrid virtual-router-id
virtual-ip virtual-address
Use the command...
system-view
interface interface-type interface-
number
vrrp ipv6 vrid virtual-router-id
priority priority-value
vrrp ipv6 vrid virtual-router-id

vrrp ipv6 vrid virtual-router-id

Remarks
Optional
By default, no global unicast address
is configured as the virtual IPv6
address of a VRRP group
