gigabitethernet 1/0/1
OL-32598-01
Purpose
Enables privileged EXEC mode.
• Enter your password if prompted.
Enters the global configuration mode.
Enables IP multicast routing.
IP multicast routing is supported with Multicast Forwarding Information Base
(MFIB) and Multicast Routing Information Base (MRIB).
Specifies the Layer 3 interface on which you want to enable multicast routing,
and enters interface configuration mode.
The specified interface must be one of the following:
• A routed port—A physical port that has been configured as a Layer 3 port
by entering the no switchport interface configuration command. You
will also need to enable IP PIM sparse-dense-mode on the interface, and
join the interface as a statically connected member to an IGMP static
group. For a configuration example, see
as a Routed Port, on page 95
• An SVI—A VLAN interface created by using the interface vlan vlan-id
global configuration command. You will also need to enable IP PIM
sparse-dense-mode on the VLAN, join the VLAN as a statically connected
member to an IGMP static group, and then enable IGMP snooping on the
