Enabling Pim-Sm - HP ProCurve Secure Router 7203 dl Advanced Management And Configuration Manual

Enabling PIM-SM

You must enable PIM-SM on every interface that connects to a network in the
PIM domain. These networks include:
LAN networks with hosts that may join the multicast groups
LAN networks through which multicast traffic must transit
WAN networks through which multicast traffic will travel between remote
sites
The Layer 2 interfaces on the ProCurve Secure Router that support PIM-SM
are:
Ethernet interfaces
Ethernet subinterfaces (VLAN interfaces)
PPP interfaces
Frame Relay subinterfaces
ATM subinterfaces
HDLC interfaces
To enable PIM-SM on an individual interface, move to that interface's config-
uration mode context. Then enter this command:
Syntax: ip pim sparse-mode
For example:
ProCurve(config)# interface frame-relay 1.101
ProCurve(config-fr 1.101)# ip pim sparse-mode
The interface will now listen for and send PIM join/prune messages.
PIM-SM works with IGMP. An edge router adds an interface to the outgoing
interface list for a group only when it receives an IGMP report for that group
on that interface. The ip pim sparse-mode command automatically enables
the interface to act as an IGMP server. (See Chapter 10: Configuring Multi-
cast Support for a Stub Network for more information on setting IGMP
settings.)
After enabling PIM-SM on all interfaces, you should access the PIM sparse
configuration mode context. Move to the global configuration mode context
and enter:
ProCurve(config)# router pim-sparse
ProCurve(config-pim-sparse)#
