Configuring Basic Functions of IGMP 529
Configuring an IGMP version for an interface
Follow these steps to configure an IGMP version on an interface:
c
CAUTION: All devices on the same subnet must run the same version of IGMP,
and cannot automatically switch between different IGMP versions.
Configuring a Static
Member of a Multicast
Group
After being configured as a static member of a multicast group, an interface it will
act as a virtual member of the multicast group to receive multicast data addressed
to that multicast group for the purpose of testing multicast data forwarding.
Before you can configure an interface of a PIM-SM device as a static member of a
multicast group, if the interface is PIM-SM enabled, it must be a PIM-SM DR; if this
interface is IGMP enable but not PIM-SM enabled, it must an IGMP querier. For
more information about PIM-SM and a DR, refer to
“PIM Configuration” on page
563.
Follow these steps to configure an interface as a statically connected member of a
multicast group:
n
This command does not trigger any IGMP message, and a device that has statically
joined a multicast group is not a real member of that group.
Configuring a Multicast
Group Filter
To restrict the hosts on the network attached to an interface from joining certain
multicast groups, you can set an ACL rule on the interface as a packet filter that
limits the range of multicast groups that the interface serves.
Follow these steps to configure a multicast group filter:
