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:
Configure an access list that details the multicast groups that can use the static RP
1.
router (in this case, all globally scoped multicast groups).
host1(config)#ipv6 access-list boston permit ff0e::/16 any
Specify a static RP router.
2.
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.
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.
Use to define a router as a BSR candidate.
To assign an interface from which the router should send messages, 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.
