Configuring Optional Multicast Routing Features
Configuring the Switch as a Statically Connected Member
Sometimes there is either no group member on a network segment or a host cannot report its group
membership by using IGMP. However, you might want multicast traffic to go to that network segment.
These are ways to pull multicast traffic down to a network segment:
•
•
Beginning in privileged EXEC mode, follow these steps to configure the switch itself to be a statically
connected member of a group (and enable fast switching). This procedure is optional.
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
ip igmp static-group group-address
Step 4
end
Step 5
show ip igmp interface [interface-id]
Step 6
copy running-config startup-config
To remove the switch as a member of the group, use the no ip igmp static-group group-address interface
configuration command.

Use the ip igmp join-group interface configuration command. With this method, the switch accepts
the multicast packets in addition to forwarding them. Accepting the multicast packets prevents the
switch from fast switching.
Use the ip igmp static-group interface configuration command. With this method, the switch 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 switch itself is not a member, as evidenced
by lack of an L (local) flag in the multicast route entry.
