• Entering no router pim command to disable PIM does not require a software reload.
• Entering a no router pim command removes all configuration for PIM multicast on a Layer 3
Switch (router pim level) only.
Globally enabling and disabling PIM without deleting the multicast configuration
As stated above entering a no router pim command deletes the PIM configuration. If you want to
disable PIM without deleting any PIM configuration, enter the following command.
PowerConnect(config)#router pim
PowerConnect(config-pim-router)#disable-pim
Syntax: [no] disable-pim
Use the [no] version of the command to re-enable PIM.
Configuring PIM interface parameters
After you enable IP multicast routing and PIM Sparse at the global level, you must enable it on the
individual interfaces connected to the PIM Sparse network. To do so, use the following CLI method.
To enable PIM Sparse mode on an interface, enter commands such as the following.
PowerConnect(config)#interface ethernet 2
PowerConnect(config-if-2)#ip address 207.95.7.1 255.255.255.0
PowerConnect(config-if-2)#ip pim-sparse
Syntax: [no] ip pim-sparse
The commands in this example add an IP interface to port 2, then enable PIM Sparse on the
interface.
If the interface is on the border of the PIM Sparse domain, you also must enter the following
command.
PowerConnect(config-if-2)#ip pim border
Syntax: [no] ip pim border
NOTE
You cannot configure a routing interface as a PMBR interface for PIM Sparse in the current software
release.
Configuring BSRs
In addition to the global and interface parameters in the sections above, you need to identify an
interface on at least one Layer 3 Switch as a candidate PIM Sparse Bootstrap router (BSR) and
candidate PIM Sparse Rendezvous Point (RP).
NOTE
It is possible to configure the Layer 3 Switch as only a candidate BSR or RP, but Dell recommends
that you configure the same interface on the same Layer 3 Switch as both a BSR and an RP.
This section presents how to configure BSRs. Refer to “Configuring RPs” on page 482 for
instructions on how to configure RPs.
To configure the Layer 3 Switch as a candidate BSR and RP, enter commands such as the following.
