PIM Multicast Routing
– 1024 –
◆
To use multicast routing, IGMP proxy cannot be enabled on any interface of the
device (see the
ip igmp proxy command).
Example
Console(config)#router pim
Console(config)#exit
Console#show ip pim interface
PIM is enabled.
VLAN 1 is up.
PIM Mode : Dense Mode

Hello Interval : 30 sec
Hello HoldTime : 105 sec
Triggered Hello Delay : 5 sec
Join/Prune Holdtime : 210 sec
Lan Prune Delay : Disabled
Propagation Delay : 500 ms
Override Interval : 2500 ms
Graft Retry Interval : 3 sec
Max Graft Retries : 3
State Refresh Ori Int : 60 sec
Console#
ip pim
This command enables PIM-DM or PIM-SM on the specified interface. Use the no
form to disable PIM-DM or PIM-SM on this interface.
Syntax
[ no ] ip pim { dense-mode | sparse-mode }
dense-mode - Enables PIM Dense Mode.
sparse-mode - Enables PIM Sparse Mode.
Default Setting
Disabled
Command Mode
Interface Configuration (VLAN)
Command Usage
◆
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 pim command, and also enable PIM-DM or PIM-SM 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. Sparse mode interfaces are added only when periodic
