Create an operational group. Do not enable BDF Interface monitoring. See To create an operational group.

Configure a VRRP instance on either a base router, IES interface, or VPRN interface. In the Operational Group panel, add the operational group created in Stage 1.

See one of the following:

• To create a VRRP instance on an IES L3 access interface for a virtual router

• To create a VRRP instance on a VPRN L3 access interface for a virtual router

• To create and configure a VRRP instance

Configure a PIM interface on the instance. Configure the Designated Router parameters in the Behavior tab to ensure that the Operational DR Priority is the highest priority on the interface if the monitored group is up. For example, if Delta Priority Action is set to Add, Operational DR Priority is equal to DR Priority plus Operational Group Delta Priority.
