PIM Multicast Routing
◆
To use multicast routing, IGMP proxy can not enabled on any interface
of the device (see the
ip igmp proxy command).
E
XAMPLE
Console(config)#router pim6
Console(config)#
ipv6 pim dense-
mode
This command enables IPv6 PIM-DM on the specified interface. Use the no
form to disable IPv6 PIM-DM on this interface.

◆
To fully enable PIM, you need to enable multicast routing globally for
the router with the
ip multicast-routing command, enable PIM globally
for the router with the router pim6 command, and also enable PIM-DM
for each interface that will participate in multicast routing with this
command.
◆
If you enable PIM on an interface, you should also enable IGMP on that
interface. PIM mode selection determines how the switch populates the
multicast routing table, and how it forwards packets received from
directly connected LAN interfaces.Dense mode interfaces are always
added to the multicast routing table.
◆
Dense-mode interfaces are subject to multicast flooding by default, and
are only removed from the multicast routing table when the router
determines that there are no group members or downstream routers,
or when a prune message is received from a downstream router.
