Configuring BSR and RP Candidates for PIM Sparse Mode
ip pim bsr-candidate

host1(config)#ip pim send-rp-announce loopback 2 scope 23 group-list boston interval
200
Use the no version to clear filters from this interface.
See ip pim send-rp-announce.
Use to configure the router as an RP mapping agent, which records group-to-RP
mappings and notifies PIM designated routers about the mappings.
Specify the number of hops for which the RP discovery message is valid; default value
is 64.
To assign an interface from which the router sends auto-RP discovery 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.
Example
host1(config)#ip pim send-rp-discovery scope 23 loopback 1
Use the no version to stop the router from acting as an RP mapping agent.
See ip pim send-rp-discovery scope.
When choosing candidate BSRs, 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 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.
Use to define a router as a BSR candidate.
To assign an interface from which the router sends 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 32 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 24 limits the group address to
the first 24 bits. The default hash mask length is 30 bits.
Use the priority keyword to specify a value for the BSR-priority field of BSMs that the
router originates. In the BSR election process, the BSR with the higher priority is
preferred. If the priority values are equal, the router with the higher IP address becomes
the BSR. The default value is 0 (address comparison only).
Use the period keyword to specify the interval, in the range 1–65535 seconds, at which
the BSR sends bootstrap messages. The default value is 60 seconds.
