Configuring the Device as a Statically Connected Member (CLI)
At various times, either there is not a group member on a network segment or a host that cannot report its
group membership by using IGMP. However, you may want multicast traffic to be sent to that network
segment. The following commands are used to pull multicast traffic down to a network segment:
• ip igmp join-group—The device accepts the multicast packets in addition to forwarding them. Accepting
the multicast packets prevents the device from fast switching.
• ip igmp static-group—The device does not accept the packets itself, but only forwards them. This
method enables fast switching. The outgoing interface appears in the IGMP cache, but the device itself
is not a member, as evidenced by lack of an L (local) flag in the multicast route entry.
This procedure is optional.
