Configuring PIM-SM
To configure PIM-SM on a router, you must:
enable PIM-SM on router interfaces
specify the RP
PIM-SM relies on RPF to determine upstream neighbors. The protocol works
with whatever routing methods the router uses, including:
static routing
Routing Internet Protocol (RIP)
Open Shortest Path First (OSPF)
Border Gateway Protocol (BGP)
You must implement one or more of these routing methods in order for PIM-
SM to function. See Chapter 15: IP Routing—Configuring RIP, OSPF, BGP,
and PBR.
The routing table must include an explicit route to each potential RP and
multicast source. Default routes are not sufficient. For example, if your
network uses OSPF and your router is in a total stub area, the router will only
receive a default route for inter-area traffic. It will not be able to use RPF to
determine its upstream neighbors for RPs and sources outside of its area. You
should remove the no-summary option from the area <area ID> stub OSPF
command.
When configuring PIM-SM on the ProCurve Secure Router, you can optionally:
configure multiple static RPs, each of which is responsible for a specific
multicast group or groups
change the threshold for switching to an SP tree
force the router to use the RP tree permanently
change an interface's DR priority
change PIM-SM timers
