1. 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

2. Specify a static RP router.

host1(config)#ipv6 pim rp-address ::122:1 boston

ipv6 pim rp-address

• 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.

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.

ipv6 pim bsr-candidate

• 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.

• Specify a length (up to a 128 bits) for the hash mask length field sent in BSMs that the

router originates. This mask is combined with the group address before the router calls

the hash function. For example, specifying a value of 32 limits the group address to the

first 32 bits. The default and maximum hash mask length is 126 bits.
