Configuring an RP Router for PIM Sparse Mode

When you use the router for PIM sparse mode, some VRs must act as RP routers. If
you want to control PIM more tightly, you can configure a static RP router. To do so:

Configuring BSR and RP Candidates for PIM Sparse Mode

When choosing candidate BSRs or candidate RPs, select well-connected routers in
the core of the network.
Typically, candidate BSRs are a subset of the candidate RPs. A single BSR is elected
for the domain the set of candidate BSRs. The elected BSR floods bootstrap messages
(BSMs) containing their group-to-RP mappings to all PIM routers. PIM routers use the
group-to-RP mappings supplied by the elected (or preferred) BSR.
Candidate RPs are routers that are capable of performing as a rendezvous point
router for one or more multicast groups. Candidate RPs periodically advertise the
set of groups they support to BSRs. A candidate RP may support all the multicast
group address range or any subset thereof. You can achieve redundancy by
configuring more than one candidate RP for a group or range of groups.

Configuring an RP Router for PIM Sparse Mode

In Interface Configuration mode:
host1(config-subif)#ipv6 pim join-prune-interval 150
Use the no version to restore the default value, 60 seconds.
Configure an access list that details the multicast groups that can use the static
RP router (in this case, all globally scoped multicast groups).
host1(config)#ipv6 access-list boston permit ff0e::/16 any
Specify a static RP router.
host1(config)#ipv6 pim rp-address ::122:1 boston
Use to specify a static PIM RP router.
Specify a standard IPv6 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)#ipv6 pim rp-address 2001::1 76 override
Use the no version to clear the filter from this interface.
See ipv6 pim rp-address.
