Creating A Vrrp Group And Assigning A Virtual Ipv6 Address - HP VSR1000 High Availability Configuration Manual

Creating a VRRP group and assigning a virtual IPv6 address

A VRRP group can work correctly after you create it and assign at least one virtual IPv6 address for it. You
can configure multiple virtual IPv6 addresses for the VRRP group on an interface that connects to multiple
subnets for router backup.
Configuration guidelines
If a router is the IP address owner in a VRRP group, do not configure the ospfv3 area command on
•
the interface to use the IPv6 address of the interface or the virtual IPv6 address of the VRRP group,
to establish an OSPFv3 neighbor relationship with the adjacent router. For more information about
the ospfv3 area command, see Layer 3—IP Routing Command Reference.
In load balancing mode, the virtual IPv6 address of a VRRP group cannot be the same as the IPv6
•
address of any interface in the VRRP group.
The maximum number of VRRP groups that you can create on an interface is 8. The maximum
•
number of virtual IPv6 addresses that you can assign for a VRRP group is 16.
If you create an IPv6 VRRP group but do not assign any virtual IPv6 addresses to it, the VRRP group
•
stays in inactive state and does not function.
• To avoid IP address collisions, change the IPv6 address of the interface on the IP address owner
before you remove the VRRP group from the interface.
The virtual IPv6 addresses of an IPv6 VRRP group and the IPv6 address of the interface where the
•
VRRP group is configured must be in the same subnet. Otherwise, hosts on the subnet cannot access
external networks.
Configuration procedure
To create a VRRP group and assign a virtual IPv6 address:
Step
1. Enter system view.
2. Enter interface view.
3. Create a VRRP group and
assign a virtual IPv6 address,
which is a link-local address.
4. (Optional.) Assign a virtual
IPv6 address, which is a
global unicast address.

Remarks
N/A
N/A
By default, no VRRP group exists.
The first virtual IPv6 address that
you assign to an IPv6 VRRP group
must be a link-local address, and it
must be the last address you
remove. Only one link local
address is allowed in a VRRP
group.
By default, no global unicast
address is assigned for an IPv6
VRRP group.
