R0106-HP MSR Router Series High Availability Command Reference(V7)

51
The first virtual IPv6 address that you assign for an IPv6 VRRP group must be a link-local address, and it
must be removed last.
An IPv6 VRRP group can have only one link-local address as its virtual IPv6 address.
If you create an IPv6 VRRP group but do not assign any virtual IPv6 address for it, the VRRP group stays
in inactive state and does not function.
The virtual IPv6 addresses of an IPv6 VRRP group must be in the same subnet as one of the IPv6
addresses of the interface where the VRRP group is configured. Otherwise, the hosts in the subnet cannot
access external networks.
Examples
# Create IPv6 VRRP group 1 and assign virtual IPv6 address fe80::10 to the VRRP group. Then assign
virtual IPv6 address 1::10 to the VRRP group.

vrrp ipv6 vrid weight track
Use vrrp ipv6 vrid weight track to configure the VFs in an IPv6 VRRP group to monitor a track entry in
load balancing mode. When the state of the track entry transits to Negative, the weight values of all VFs
in the VRRP group on the router decrease by a specific value.
Use undo vrrp ipv6 vrid weight track to remove the association between the VFs in an IPv6 VRRP group
and a track entry.
Syntax
vrrp ipv6 vrid virtual-router-id weight track track-entry-number [ reduced weight-reduced ]
undo vrrp ipv6 vrid virtual-router-id weight track [ track-entry-number ]
Default
The VFs in an IPv6 VRRP group are not associated with any track entry.

Parameters
virtual-router-id: Specifies an IPv6 VRRP group by its virtual router ID in the range of 1 to 255.
track-entry-number: Specifies a track entry by its number in the range of 1 to 1024.
reduced weight-reduced: Reduces the weights of the VFs in the IPv6 VRRP group by a specific value when
the state of the specified track entry changes to negative. The weight-reduced argument is in the range
of 1 to 255.
