Quick Start
This section provides the commands you must enter to quickly configure PIM-
SM for multicast routing. Only a minimal explanation is provided.
If you need additional information about any of these options, see "Contents"
on page 11-1 to locate the section and page number that contains the expla-
nation you need.
1. Enable PIM-SM on each interface that connects to a network that must
support or transit multicasts. Move to the interface configuration mode
context and enter this command:
Syntax: ip pim sparse-mode
For example, enable PIM-SM on a LAN and a WAN interface:
ProCurve(config)# interface eth 0/1
ProCurve(config-eth 0/1)# ip pim sparse-mode
ProCurve(config-eth 1)# interface frame-relay 1.1
ProCurve(config-fr 1.1)# ip pim sparse-mode
2. Move to the PIM sparse configuration mode context:
Syntax: router pim-sparse
3. Specify the IP address of the RP:
Syntax: rp-address <A.B.C.D>
For example:
ProCurve(config-pim-sparse)# rp-address 10.1.1.1
You must configure the same RP address on every router that runs PIM in your
network.
The steps above are sufficient for routing multicasts between remote sites in
many WAN environments. You can use the following commands to set up more
complex features:
4. You can alter when the router switches to an SP tree. Specify the number
of packets that the router must receive from a source before it joins the
SP tree with this command, entered from the PIM sparse configuration
mode context:
Syntax: spt-threshold <packets>
