Multicast Migration
You can enable the flow of multicast traffic over either multicast (DVMRP or
MOSPF) or nonmulticast, IGMP static router interfaces. To enable the transfer of
packets between multicast and nonmulticast networks, you must create one or
more of the following:
• IP traffic filters
• IGMP static forwarding policies
• Multicast protocol policies (DVMRP or MOSPF)
You must configure IGMP on any interface running a multicast protocol, as well
as on any static interface over which you want to transfer multicast traffic.
You can also allow unicast packets to travel as multicast and multicast packets as
unicast between multicast and nonmulticast networks. Table 1-1 provides an
overview of how different packet types can travel between multicast and
nonmulticast networks.
