DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode. Enter your password if prompted.enable
Step 1
Example:
Device> enable
Enters the global configuration mode.configure terminal
Example:
Device# configure terminal
Step 2
Selects an interface on which to statically forward traffic for a multicast group
using SSM mapping, and enters interface configuration mode.
interface interface-id
Example:
Device(config)# interface
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 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 VLAN, the IGMP static group, and physical interface. For a
configuration example, see Example: Interface Configuration as an SVI,
on page 96
These interfaces must have IP addresses assigned to them.
Static forwarding of traffic with SSM mapping works with either
DNS-based SSM mapping or statically configured SSM mapping.
