PIM-SM (Sparse Mode)
Configuring PIM-SM on the Router

Example of Configuring PIM-SM Support in a VLAN Context

PIM-SM support must be configured in each VLAN where you want PIM-SM
forwarding of multicast traffic. This example illustrates the following per-
VLAN configuration steps:

Enabling PIM-SM on VLAN 120 and allow the default “any” option to select
a source IP address for PIM-SM packets forwarded from this VLAN.
(Because the VLAN in this example is configured with only one IP
address—120-10.10.2—it is this address that will be used for the source.)

Increasing the Designated Router (DR) priority on this VLAN from the
default 1 to 100.

Leaving the other per-VLAN PIM-SM fields in their default settings.

ProCurve(config)# vlan 120

ProCurve(vlan-120)# ip pim-sparse

ProCurve(vlan-120-pim-sparse)# dr-priority 100

ProCurve(vlan-120-pim-sparse)# show ip pim interface 120

PIM Interface

VLAN : 120

IP Address : 120.10.10.2

Mode : sparse

The IP Address and Designated Router address correspond to
the source IP address most recently configured on the VLAN.

Indicates PIM-SM enabled.

Designated Router : 120.10.10.2

Hello Interval (sec) : 30

Hello Delay (sec)

: 5

Override Interval (msec) : 2500 Lan Prune Delay

Propagation Delay (msec) : 500 Lan Delay Enabled

Neighbour Timeout : 180 DR Priority

: Yes

: Yes

: 100

Increased DR Priority

All other settings remain
at their default-enabled
values.
