Configuring an RP Router for PIM Sparse Mode and PIM Sparse-Dense Mode

When you use the router for PIM sparse mode or PIM sparse-dense mode, some VRs
must act as RP routers. You can configure static RP routers or configure the router
to assign RP routers automatically.
To configure the router to assign RP routers automatically, you must define several
VRs as RP routers and one VR as an RP mapping agent. RP routers send their
announcement messages to the RP mapping agent, which assigns groups to RP
routers and resolves any conflicts. The RP mapping agent notifies neighbors of the
RP assigned to each group.

Configuring a Static RP Router

If you want to control PIM more tightly, you can configure a static RP router. To do
so:
1.
2.

Configuring an Auto-RP Router for PIM Sparse Mode

Two multicast groups, 224.0.1.39 and 224.0.1.40, are reserved for forwarding auto-RP
messages through the network. When you configure an auto-RP router for PIM sparse
mode, you must assign a static RP router to these two groups. You can then specify
an RP mapping agent for other multicast groups.
To configure an auto-RP router for PIM sparse mode:
1.
90

Configuring an RP Router for PIM Sparse Mode and PIM Sparse-Dense Mode

Use to set an interval value, in the range 10–210 seconds, at which the router
sends the PIM join/prune message; the default value is 60 seconds.
Examples
In Router Configuration mode:
host1(config-if)#ip pim join-prune-interval 150
In Interface Configuration mode:
host1(config-subif)#ip pim join-prune-interval 150
Use the no version to restore the default value, 60 seconds.
Configure an access list that specifies the multicast groups that can use the static
RP router.
host1(config)#access-list boston permit 228.0.0.0 15.255.255.255
Specify a static RP router.
host1(config)#ip pim rp-address 122.0.0.1 1 boston
Configure a static RP to have priority over the auto-RP for the groups that send
auto-RP multicast messages.
