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.
•
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.
