Configuring VRRP VRRP Configuration Overview
OmniSwitch AOS Release 8 Network Configuration Guide December 2017 page 23-16
After creating a virtual router group, you have to add virtual routers to the group using the vrrp group-
association command. For example:
-> vrrp 10 1 group-association 25
The above command adds the virtual router 10 on VLAN 1 to the virtual router group 25. A virtual router
need not be disabled in order to be added to a virtual router group. However, the virtual router will not
adopt the group’s default parameter values until those values are applied by reenabling the virtual router.
To remove a virtual router from a virtual router group, use the no form of the same command as follows:
-> vrrp 10 1 no group-association 25
Note that a virtual router need not to be disabled to be removed from a group.
You can change the default values of the parameters like advertising interval, priority and preempt of all
the virtual routers in a virtual router group using the vrrp group command, as follows:
-> vrrp group 25 advertising interval 50 priority 50 no preempt
The above command configures the default value for advertising interval as 50 seconds, priority as 150
and preempting mode as no preempt. These parameters can be modified at any time but will not have any
effect on the virtual routers in the group until you disable, then apply the group default value using the
vrrp group set command and enable the virtual router group again.
For the modified default values to be applied to the virtual routers in a group, you must disable the virtual
router group, then apply the group default value using the vrrp group set command and enable the virtual
router group again. For example:
-> vrrp group 25 interval 50
-> vrrp group 25 admin-state disable
-> vrrp group 25 set interval
-> vrrp group 25 admin-state enable
The first command configures the default interval value as 50 for all the virtual routers in the virtual router
group 25. The next command disables all the virtual routers in the group. The vrrp group set command in
this sequence applies the new default interval value to all the virtual routers in the group. This value will
be applied only to the virtual routers in the group that already have the default value and not the values
configured individually. This is because the configured values take priority over the default values.
For the modified default values to affect the virtual routers in the group, including the virtual routers that
are configured with a value individually, you can use the vrrp group set command along with the
override option. For example:
-> vrrp group set interval override
The next command enables all the virtual routers in the group except the virtual routers that are disabled
individually. To enable all the virtual routers in the group including those which are disabled individually,
you can use the vrrp group command with the enable-all option as follows:
-> vrrp group 25 admin-state enable-all
Note. You can specify a parameter such as interval, priority, preempt or all in the vrrp group set command
to set and/or override the existing value with the new default values. The all option resets and/or overrides
the existing advertising interval value, priority value and preempt mode with the modified default values.
Note. Even though a virtual router may be assigned to a group, its parameter values and administrative
status can still be modified individually.
