PIM dense

The primary difference between PIM DM V1 and V2 is the methods the protocols use for
messaging:
•
PIM DM V1 – uses the IGMP to send messages.
•
PIM DM V2 – sends messages to the multicast address 224.0.0.13 (ALL-PIM-ROUTERS) with
protocol number 103.
The CLI commands for configuring and managing PIM DM are the same for V1 and V2. The only
difference is the command you use to enable the protocol on an interface.
NOTE
If you want to continue to use PIM DM V1 on an interface, you must change the version, then save
the configuration.
NOTE
The note above does not mean you can run different PIM versions on devices that are connected to
each other. The devices must run the same version of PIM. If you want to connect a device running
PIM to a device that is running PIM V1, you must change the PIM version on the device to V1 (or
change the version on the device to V2, if supported).
Configuring PIM DM
NOTE
This section describes how to configure the “dense” mode of PIM, described in RFC 1075. Refer to
on page 680 for information about configuring PIM Sparse.
Enabling PIM on the router and an interface
By default, PIM is disabled. To enable PIM:
•
Enable the feature globally.
•
Configure the IP interfaces that will use PIM.
•
Enable PIM locally on the ports that have the IP interfaces you configured for PIM.
•
Reload the software to place PIM into effect.
Suppose you want to initiate the use of desktop video for fellow users on a sprawling campus
network. All destination workstations have the appropriate hardware and software but the Brocade
routers that connect the various buildings need to be configured to support PIM multicasts from
the designated video conference server as shown in
PIM is enabled on each of the Brocade routers shown in
, on which multicasts are
expected. You can enable PIM on each router independently or remotely from one of the routers
with a Telnet connection. Follow the same steps for each router. A reset of the router is required
when PIM is first enabled. Thereafter, all changes are dynamic.
Globally enabling and disabling PIM
To globally enable PIM, enter the following command.
BigIron RX(config)# router pim
Syntax: [no] router pim
