PIM-SM (Sparse Mode)
Configuration Steps for PIM-SM

b. Use

ip pim-sparse to enter the VLAN’s pim-sparse context and do one

of the following:
–

Enable PIM-SM on the VLAN and allow the default option (

any)

to dynamically determine the source IP address for the PIM-SM
packets sent from this VLAN interface.

–

Enable PIM-SM on the VLAN and specify an IP address for the
PIM-SM packets sent from this VLAN interface. (The specified IP
address must already be statically configured on the VLAN.)

(This step requires enabling

router pim on the global configuration

context. Refer to step 3 on page 4-21.)

c. In the VLAN’s

pim-sparse context, you also have the option to change

the current DR priority (default = 1) to the value wanted for the
current router in the current VLAN. (Use

dr-priority < 0 - 4294967295 >.)

N o t e

When you initially enable PIM-SM, ProCurve recommends that you leave the
PIM-SM traffic control settings (listed in the next step) at their default settings.
You can then assess performance and make configuration changes where a
need appears.

4. This is an optional step in the initial PIM-SM configuration. (Refer to the

preceding Note.) In the

pim-sparse context of a given VLAN on which PIM

SM is enabled, change one or more of the traffic control settings listed in
the following table. (Note that some VLAN context control settings apply
to both PIM-SM and PIM-DM.)
