Multicast
PIM (Protocol
Independent Multicast)
multicast routing protocol
routes multicast traffic
use any of the unicast routing protocols to identify the path
PIM operating modes
PIM Dense Mode (PIM-DM)
multicast traffic from the source is
flooding throughout the entire network
applicable to small networks, active receivers on every subnet of the network
PIM-DM is not generally recommended for
production environments
Sparse Mode (PIM-SM)
Sparse Dense Mode
Source Specific Multicast (PIM-SSM)
Bidirectional Mode (Bidir-PIM)
2 basic types of multicast
distribution trees
shortest path trees (SPTs)
source trees
the source is the root of the tree
it uses the shortest path through the network from the source to the leaves of the tree.
rendezvous point trees (RPTs)
shared trees
the root of the shared tree is not the source but a router designated as the rendezvous point (RP)
Multicast traffic is forwarded down the shared tree according to the group address G that the packets are addressed to
