IGMP Commands

Dell EMC Networking OS supports IGMPv1/v2/v3 and is compliant with RFC-3376.

Important Points to Remember

  • Dell EMC Networking OS supports protocol-independent multicast-sparse (PIM-SM) and protocol-independent source-specific multicast (PIM-SSM) include and exclude modes.
  • IGMPv2 is the default version of IGMP on interfaces. You can configure IGMPv3 on interfaces. It is backward compatible with IGMPv2.
  • The maximum number of interfaces supported 95.
  • There is no hard limit on the maximum number of groups supported.
  • IGMPv3 router interoperability with IGMPv2 and IGMPv1 routers on the same subnet is not supported.
  • An administrative command (ip igmp version) is added to manually set the IGMP version.
  • All commands previously used for IGMPv2 are compatible with IGMPv3.
