PIM is an advanced routing feature that must be enabled with a license key. If you have purchased an
advanced license key, and have enabled routing on the device, you must activate your license as described in
“Activating Licensed Features” on page 3-29 in order to enable the PIM command set. If you wish to purchase
an advanced routing license, contact Enterasys Networks Sales.
Note: IGMP must be enabled on all VLANs running PIM-SM, and must also be globally enabled
on the SecureStack C3 stack. For details on enabling IGMP, refer to Chapter 10.
