Protocol Independent Multicast (PIM)
These examples use PIM-SM or PIM-DM for multicast routing between three
switches. The network topology is the same for each example (Figure 3).
Multicast group management uses IGMP. The examples assume that each
switch starts from the default configuration.
Figure 3: Multicast configuration using PIM sparse or dense mode.
PIM-SM This example uses PIM Sparse Mode and allows IP hosts to send data to and
receive data from the multicast groups 225.1.0.0 to 225.1.0.255. The
configuration of Switches A, B, and C are very similar, but Switch A is the only
switch configured as a PIM Bootstrap Router Candidate and a PIM rendezvous
point candidate.
To configure Switch A
1. Set the system name for the switch.
set sys name=A-pim-rp
