  Use the following commands to configure MLD SSM Mapping in ExtremeXOS:
  
   - Enable or disable MLD SSM Mapping on a VR: [enable | disable] mld
     ssm-map { {vr} vrname }
- Add an MLD SSM Mapping entry on a VR: configure mld ssm-map add
      v6groupnetmask [v6sourceip | src_domain_name] { {vr}
     vrname}
- Delete an MLD SSM Mapping entry on a VR:configure mld ssm-map
     delete v6groupnetmask [v6sourceip | src_domain_name] { {vr}
      vrname} 
- Delete all MLD SSM Mapping entries on a VR: unconfigure mld
     ssm-map { {vr} vrname}
- Display the status of MLD-SSM mapping feature on a VR, and display the
    MLD-SSM mapping entries: show mld ssm-map { v6groupnetmask } { {vr}
      vrname }
- Send out a DNS request for a particular group. On receiving the DNS
    response, the "DNS Age" in the SSM mapping entry is refreshed: refresh mld ssm-map
      v6groupnetmask { {vr} vrname}
- Configure the DNS server: configure dns-client add name-server
      ip_address {vr vr_name}]
