HP 7102dl - ProCurve Secure Router Configuration Manual page 673

If you know precisely which groups your network must support and you
know which areas expect traffic for specific groups, you can configure a
router to support a single group. For example, the multicast video
streamer in Figure 13-11 is the only source that sends traffic to
239.255.255.1. You could associate Router A with this single group when
you configure the static RP set on each router in the WAN.

Figure 13-11. Configuring a Static RP
Remember to always configure at least one RP to support all groups so
that necessary network protocols are not blocked. You can deny the
addresses for the groups specifically supported by another router from
the list of groups supported by this default RP.
Specifying the Groups Supported by a Static RP. You use an access
control list (ACL) to associate an RP with a particular group or set of groups.
When you configure the ACL, you enter the IP address of the group or groups
that the RP supports as a permitted source.
Complete these steps to configure the ACL:
1. From the global configuration mode context, create the ACL:
Syntax: ip access-list [extended | standard] <listname>
Because you enter the multicast address as a source address, you should
use a standard ACL. For example:
ProCurve(config)# ip access-list standard RP1
You will then enter the ACL configuration mode context.
