OSPFv3 Timers
  
  
    Configuring OSPFv3 timers on a per area basis is a shortcut to applying the timers to
            each VLAN in the area at the time of configuration.
    If you add more VLANs to the area, you must configure the timers for the new VLANs explicitly. Use the
      command:
    configure ospfv3 {domain
          domainName} [vlan
          vlan-name | tunnel
          tunnel-name | [vlan | tunnel] all] timer
            {retransmit-interval} retransmit-interval
            {transit-delay} transit-delay {hello-interval}
            hello-interval {dead-interval}
        dead-interval
