host1(config)#ip pim send-rp-discovery scope 23 loopback 1
2. Configure an access list that details the multicast groups that can use the static RP
router.
host1(config)access-list boston permit 224.0.0.0 15.255.255.255
3. Prevent routers from advertising auto-RP messages to the multicast groups that
are reserved for forwarding auto-RP messages through the network.
host1(config)#access-list 1 deny 224.0.1.39
host1(config)#access-list 1 deny 224.0.1.40
4. Configure routers to send auto-RP announcement messages to the mapping agent.
host1(config)#ip pim send-rp-announce loopback 2 scope 23 group-list boston
interval 200
ip pim rp-address
• Use to specify a static PIM RP router.
• Specify a standard IP access list of multicast groups to control which multicast groups
can use this RP router.
• Specify the override keyword if you want this static RP router to have priority over
auto-RP routers.
• Example
host1(config)#ip pim rp-address 192.48.1.22 11 override
• Use the no version to clear the filter from this interface.
• See ip pim rp-address.
ip pim send-rp-announce
• Use to send auto-RP announcement messages from a router you configured as an RP.
• Specify an interface type and specifier, such as atm 3/0. For details about interface
types and specifiers, see Interface Types and Specifiers in JunosE Command Reference
Guide.
• The auto-RP announcement messages contain the IP address for the interface that
you specify.
• Specify the number of hops for which the announcement is valid; default value is 64.
• Specify an access list that details which multicast groups the RP can include in
announcement messages.
• Specify a time interval in the range 1–65535 seconds to control how often the router
sends announcements. The default is 60 seconds.
• Example
host1(config)#ip pim send-rp-announce loopback 2 scope 23 group-list boston interval
200
