6.4 Adjusting Control Parameters for a Multicast Source
A multicast device can control the forwarding of multicast data based on multicast sources. This
helps to control multicast data flows and limit information that can be obtained by downstream
receivers to enhance security.
6.4.1 Establishing the Configuration Task
After basic functions of PIM-SM are configured, you can configure the lifetime of a multicast
source and source address-based filtering rules as required.
Applicable Environment
All the configurations in this section are applicable to the ASM and SSM models.
PIM switchs check the multicast data that passes by. By checking whether the data matches the
filtering rule, the switchs determine whether to forward the data. That is, the switchs in the PIM
domain function as filters. The filters help to control the data flow, and to limit the information
that the downstream receiver can obtain.
Switchs can work normally under the control of default values. The S7700 allows users to adjust
the parameters as required.
NOTE
If there is no special requirement, default values are recommended.
Pre-configuration Tasks
Before adjusting control parameters for a multicast source, complete the following tasks:
l Configuring a certain unicast routing protocol
l Configuring Basic PIM-SM Functions
Data Preparation
To adjust control parameters for a multicast source, you need the following data.
No.
Data
1 Lifetime of a multicast source
2 Filtering rules based on multicast source addresses
