6.2 PIM-SM Features Supported by the S7700

The system can work normally with default PIM-SM parameters. You are also allowed to adjust
parameters related to neighbor discovery, forwarding, DR, RP, join, register, and assert. In
addition, you can configure various filtering policies and the PIM silent function to enhance the
PIM-SM security. PIM-SM supports SSM, PIM BFD, PIM GR, and SPT switchover.
Basic PIM-SM Functions
PIM-SM supports the ASM and SSM models. You can set the range of ASM group addresses
or the range of SSM group addresses.
Static RP
You can specify a static RP on all the switchs in a PIM-SM domain. When a dynamic RP exists
in the domain, the dynamic RP is preferred by default, but you can configure the static RP to be
preferred.
Dynamic RP
You can configure C-RPs and C-BSRs in a PIM-SM domain and set the unified rules used to
dynamically generated the BSR and the RP. You can adjust the priority for C-RP election, adjust
the lifetime of the advertisement message on the BSR received from the C-RP, adjust the interval
for the C-RP to send advertisement messages, and specify an Access Control List (ACL) to limit
the range of the multicast groups served by the C-RP.
BSR
You can specify the C-BSR in the BSR domain, adjust the hash length used by the RP for C-RP
election, adjust the priority used for BSR election, and adjust the legal BSR address range. To
limit the transmission of BSR messages, you can configure the BSR service boundary on an
interface of the switch on the boundary of the BSR domain.
Filtering Policy Based on Source Addresses
You can configure filtering rules of the multicast source address to control multicast sources.
You can configure the policy to filter Register messages, and suppress PIM-SM Register
messages.
BSR Administrative Domain
You can configure the service boundary of the BSR administrative domain and the boundary of
the administrative domain by using the related commands.

NOTE
l The Protocol Independent Multicast Dense Mode (PIM-DM) is applicable to a small-scale network
with densely distributed members.
l PIM-SM can be used to construct the Any-Source Multicast (ASM) and Source-Specific Multicast
(SSM) models.
