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.
