How do we add a muticast address, is there any application which can = > generate a set of multicast address which can be added to the driver. the application to driver interface to add/delete a multicast group is through the SIOCADDMULTI/SIOCDELMULTI ioctl() calls. Your driver must do the steps to implement the adding/deleting of the group for your card. applications in /usr/ports/mbone will add and delete multicast groups. So will mrouted (the Multicast router) if connected to a tunnel, pimd if in a PIM environment, many routing protocols connect to the "Multicast All Router's group" and IPv6 uses multicast instead of broadcast.
