Configuring VRRP

Enabling/Disabling a Virtual Router

To administratively enable a virtual router, use the vrrp or vrrp3 command option with the admin-state
enable keyword. Note that at least one IPv4 address must be configured for a VRRPv2 virtual router
before the virtual router can be enabled; this is not a requirement for VRRPv3 virtual routers. For
example:
-> vrrp 6 4 priority 150
-> vrrp 6 4 address 10.10.2.3
-> vrrp 6 4 admin-state enable
-> vrrp3 10 5 priority 150
-> vrrp3 10 5 address 213:100:1::56
-> vrrp3 10 5 admin-state enable
In this example, a VRRPv2 virtual router is created on VLAN 4 with a VRID of 6 and a VRRPv3 virtual
router is created on VLAN 5 with a VRID of 10. An IPv4 address is then assigned to the VRRPv2 virtual
router and an IPv6 address is then assigned to the VRRPv3 virtual router. Both virtual routers are then
enabled on the switch.
To disable a virtual router, use the admin-state disable keyword.
-> vrrp 6 4 admin-state disable
-> vrrp3 10 5 admin-state disable
A virtual router must be disabled before it can be modified. Use the vrrp or vrrp3 command option to
disable the virtual router first; then use the command again to modify the parameters. For example:
-> vrrp 6 4 admin-state disable
-> vrrp 6 4 priority 200
-> vrrp 6 4 admin-state enable
-> vrrp3 10 5 admin-state disable
-> vrrp3 10 5 priority 200
-> vrrp3 10 5 admin-state enable
In this example, VRRPv2 virtual router 6 on VLAN 4 and VRRPv3 virtual router 10 on VLAN 5 are
disabled. Both virtual routers are then modified to change their priority setting. (For information about
configuring the priority setting, see
priority settings are changed, the virtual routers are then re-enabled and will be active on the switch.

Setting VRRP Traps

A VRRP router has the capability to generate VRRP SNMP traps for events defined in the VRRP SNMP
MIB. There are two vrrp|vrrp3 trap
•
vrrp trap—enables or disables trap generation for a VRRPv2 virtual router.
•
vrrp3 trap—enables or disables trap generation for a VRRPv3 virtual router.
In order for VRRP traps to be generated correctly, traps in general must be enabled on the switch through
the SNMP CLI. See the OmniSwitch AOS Release 8 Switch Management Guide for more information
about enabling SNMP traps globally.
