Configuring Global Parameters - Foundry Networks Switch and Router Installation And Configuration Manual

Foundry Switch and Router Installation and Configuration Guide
• Configure the following interface parameters:
• Configure an IP address on the interface
• Enable PIM Sparse.
• Identify the interface as a PIM Sparse border, if applicable.
NOTE: You cannot configure a Foundry routing interface as a PMBR interface for PIM Sparse in the current
software release.
• Configure the following IPM Sparse global parameters:
• Identify the Layer 3 Switch as a candidate PIM Sparse Bootstrap Router (BSR), if applicable.
• Identify the Layer 3 Switch as a candidate PIM Sparse Rendezvous Point (RP), if applicable.
• Specify the IP address of the RP (if you want to statically select the RP).
NOTE: Foundry Networks recommends that you configure the same Layer 3 Switch as both the BSR and
the RP.

Configuring Global Parameters

To configure the PIM Sparse global parameters, use either of the following methods.
USING THE CLI
To configure basic global PIM Sparse parameters, enter commands such as the following on each Layer 3 Switch
within the PIM Sparse domain:
BigIron(config)# router pim
BigIron(config-pim-router)# router rip
BigIron(config-rip-router)#
Syntax: [no] router pim
Syntax: [no] router rip
NOTE: You do not need to globally enable IP multicast routing when configuring PIM Sparse.
The commands in this example enable IP multicast routing, enable the PIM Sparse mode of IP multicast routing,
and then enable RIP. For simplicity, this example does not show configuration of specific RIP parameters. In
addition, the commands in this example do not configure the Layer 3 Switch as a candidate PIM Sparse Bootstrap
Router (BSR) and candidate Rendezvous Point (RP). You can configure a Foundry Layer 3 Switch as a PIM
Sparse router without configuring the Layer 3 Switch as a candidate BSR and RP. However, if you do configure
the Layer 3 Switch as one of these, Foundry Networks recommends that you configure the Layer 3 Switch as both
of these. See "Configuring PIM Sparse Global Parameters" on page 18-15.
USING THE WEB MANAGEMENT INTERFACE
You cannot configure PIM Sparse parameters using the Web management interface.
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.
USING THE CLI
To enable PIM Sparse mode on an interface, enter commands such as the following:
BigIron(config)# interface ethernet 2/2
BigIron(config-if-2/2)# ip address 207.95.7.1 255.255.255.0
BigIron(config-if-2/2)# ip pim-sparse
