* enabled cannot be added to multicast routing entry.
* 3. Add iface_1 to multicast routing entry for site-local scope.
* 4. Verify that packet sent to the same scope as before is now
* forwarded also to iface_1.
* 5. Remove iface_1 from the multicast routing entry.
* 6. Verify that packet sent to the same scope is before is now
* NOT forwarded to iface_1 as it was removed from the list.
