Simplified administrative deployment; you need only configure PIM sparse mode on
all router interfaces and issue the necessary SSM commands (including specifying
IGMPv3 on the receiver local area network).
Support for source lists; you can use source lists, supported in IGMPv3, where only
specified sources send traffic to the SSM group.
In a PIM SSM–configured network, an E Series router subscribes to an SSM channel (by
means of IGMPv3 or by means of IGMP ssm-mapping for IGMPv2/v1 joins), requesting
to join group G and source S. The directly connected PIM sparse mode router, the
designated router of the receiver, sends an (S,G) join message to its RPF neighbor for
the source. For PIM SSM, the RP is not contacted in this process by the receiver (as
happens in normal PIM sparse mode operations).
For information about modules that support PIM on the ERX7xx models, ERX14xx models,
and the ERX310 Broadband Services Router:
See ERX Module Guide, Table 1, Module Combinations for detailed module specifications.
See ERX Module Guide, Appendix A, Module Protocol Support for information about the
modules that support PIM.
For information about modules that support PIM on the E120 and E320 Broadband
Services Routers:
See E120 and E320 Module Guide, Table 1, Modules and IOAs for detailed module
specifications.
See E120 and E320 Module Guide, Appendix A, IOA Protocol Support for information
about the modules that support PIM.
