Step 3
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.
gigabitethernet 1/0/1
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 Example: Interface
Configuration as a Routed Port, on page 83.
• 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 VLAN, the IGMP static group, and physical interface.
For a configuration example, see Example: Interface Configuration as
an SVI, on page 83.
These interfaces must have IP addresses assigned to them.
