• Preempt mode. By default, preempt mode is enabled. Use no preempt to turn it off, and preempt to
turn it back on. For more information about the preempt mode, see
.
• Accept mode.
By default, the accept mode is enabled. This mode allows the master router to accept
packets addressed to the IPv6 address owner as its own. Use the no accept mode to prevent the master
router from accepting packets addressed to the IPv6 address owner.
router from accepting packets addressed to the IPv6 address owner.
• Advertising interval (in centiseconds). Use the interval keyword with the desired number of centisec-
onds for the delay in sending VRRPv3 advertisement packets. The default is 100 centiseconds. See
.
Note. The maximum number of virtual routers supported is based on the 100 centisecond interval. A
smaller interval will result in a relatively lesser number of virtual routers.
smaller interval will result in a relatively lesser number of virtual routers.
Note. The centisecond interval cannot be less than 10 centiseconds.
The following example creates a VRRPv3 virtual router (with VRID 7) on VLAN 2 with a priority of 75,
and no preempt. VRRPv3 advertisements will be sent at intervals of 200 centiseconds:
and no preempt. VRRPv3 advertisements will be sent at intervals of 200 centiseconds:
-> vrrp3 7 2 priority 75 no preempt interval 200
Note. All VRRPv3 virtual routers with the same VRID on the same LAN should be configured with the
same advertisement interval; otherwise the network may produce duplicate IPv6 or MAC address
messages.

The vrrp3 command may also be used to specify whether the VRRPv3 virtual router is enabled or
disabled (it is disabled by default). For more information about the vrrp3 command syntax, see the
OmniSwitch CLI Reference Guide.

To delete a VRRPv3 virtual router, use the no form of the vrrp3 command with the relevant VRID and
VLAN ID. For example:

-> no vrrp3 7 3
VRRPv3 virtual router 7 on VLAN 3 is deleted from the configuration. (The virtual router does not have
to be disabled before you delete it.)

Specifying an IPv6 Address for a VRRPv3 Virtual Router
A VRRPv3 virtual router must have a link local address. By default, the virtual router link local address is
created based on the virtual router MAC address and it does not need to be configured. Additional IPv6
addresses can be configured for a virtual router and these addresses must be within the subnet of an
address configured on the interface. To specify an IPv6 address for a VRRPv3 virtual router, use the
created based on the virtual router MAC address and it does not need to be configured. Additional IPv6
addresses can be configured for a virtual router and these addresses must be within the subnet of an
address configured on the interface. To specify an IPv6 address for a VRRPv3 virtual router, use the
command and the relevant IPv6 address. For example:
-> vrrp3 6 4 address fe80::200:5eff:fe00:20a
-> vrrp3 6 4 enable
