Enabling IGMP on an Interface
Refer to “Configuring IGMP” on page 198.
Enabling PIM-SM
This configuration can be effective only after multicast is enabled.
Perform the following configuration in VLAN interface view.
Repeat this configuration to enable PIM-SM on other interfaces. Only one
multicast routing protocol can be enabled on an interface at a time.
Once enabled, PIM-DM cannot be enabled on the same interface.
Setting the PIM-SM Domain Border
After the PIM-SM domain border is configured, bootstrap messages cannot cross
the border in any direction. In this way, the PIM-SM domain can be split.
