Configuring PIM-DM

Protocol-Independent Multicasting (PIM) provides two different modes of
operation: sparse mode and dense mode. Sparse mode (SM) is designed for
networks where the probability of multicast group members is low, such as
the Internet. Dense mode (DM), on the other hand, is designed for
networks where the probability of multicast group members is high, such
as a local network.
PIM-DM is a simple multicast routing protocol that uses flood and prune
to build a source-routed multicast delivery tree for each multicast
source-group pair. It is simpler than DVMRP because it does not maintain
it's own routing table. Instead, it uses the routing table provided by the
unicast routing protocol enabled on the router interface. When the router
receives a multicast packet for a source-group pair, PIM-DM checks the
unicast routing table on the inbound interface to determine if this is the
same interface used for routing unicast packets to the multicast source
