To configure PIM multicast routing, enable multicast forwarding as
        described in Enabling Multicast Forwarding and do
        the following:
    
    - 
        Configure PIM on all IP multicast routing interfaces using
          the following command:
        
          configure pim {ipv4 | ipv6} add vlan [vlan-name | all] {dense | sparse} {passive} 
        
       - 
        To enable and configure the PIM-DM state refresh feature
          on one or all VLANs, use the following commands:
        
          configure pim {ipv4 | ipv6} state-refresh {vlan} [vlan_name | all] [on | off] 
        
        
          configure pim { ipv4 |
              ipv6 } state-refresh timer origination-interval interval
          
        
        
          configure pim {ipv4 | ipv6} state-refresh timer source-active-timer interval
          
        
        
          configure pim {ipv4 | ipv6} state-refresh ttl ttlvalue
          
        
       - 
        For PIM-SSM, specify the PIM-SSM range, enable IGMPv3,
and enable PIM-SSM on the interfaces using the following commands:
        
          configure pim {ipv4 | ipv6} ssm range [default | policy
            policy-name] 
        
        
          enable igmp {vlan
            vlan name } {IGMPv1 | IGMPv2 | IGMPv3} 
        
        
          enable pim {ipv4 | ipv6} ssm vlan [vlan_name | all] 
        
       - 
        Enable PIM on the router using the following
          command:
        
          enable pim
