7.2 PIM-SM Features Supported by the S3700

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.
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.
Adjusting Parameters for Maintaining PIM-SM Neighbors
You can adjust the following parameters about PIM-SM neighbors, including:

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.
Interval for sending Hello messages
Time period for the neighbor to hold the reachable state
Whether to receive the Hello messages with Generation IDs
Maximum delay in triggering the Hello messages
Priority for DR election
DR switching delay
Neighbor filtering function: An interface sets up neighbor relationships with only the
addresses matching the filtering rules.
Interval for sending Join messages
Time period for the downstream interface to keep the forwarding state
