IGMP Commands

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

Important Points to Remember

Dell 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.

On the S-Series, the maximum number of interfaces supported 31.

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.
