Configuring Router Priority, Preemptive Mode And Interface Tracking - HP 4800G Series Configuration Manual

Configuration procedure
Follow these steps to create VRRP group and configure its virtual IPv6 address:
To do...
Enter system view
Enter the specified
interface view
Create a VRRP group and
configure its virtual IPv6
address
For the 3Com switches 4800G, the maximum number of IPv6 VRRP groups on a switch is 32, and
the maximum number of virtual IPv6 addresses for a VRRP group is 5.
A VRRP group is removed after you remove all the virtual IPv6 addresses in it. In addition,
configurations on that VRRP group no longer take effect.
Removal of the VRRP group on the IP address owner will cause IP address collision. In such a
case, it is recommended to modify the IPv6 address of the interface on the IP address owner to
resolve the collision.
