12.4 Adjusting Control Parameters of a 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.
12.4.1 Establishing the Configuration Task
After basic functions of IPv6 PIM-DM are configured, you can configure the lifetime of a
multicast source and source address-based filtering rules as required.
Applicable Environment
This configuration is applicable to all PIM-DM networks.
PIM-IPv6 switchs check the passing multicast data packets. By checking whether the data
packets match the filtering rule, the switchs determine whether to forward the packets. That is,
the switchs in the PIM-IPv6 domain act as filters. The filters help to control data flows and limit
information obtained by downstream receivers.
Pre-configuration Tasks
Before adjusting control parameters of a source, complete the following tasks:
l Configuring a unicast routing protocol
l Configuring Basic PIM-DM (IPv6) Functions
Data Preparation
To adjust control parameters of a source, you need the following data.
No.
Data
1 Keepalive period of a source
2 Filtering rules of multicast source addresses
12.4.2 Configuring the Keepalive Period of a Source
A multicast device starts a timer for each (S, G) entry. If the multicast device does not receive
any multicast packets from a multicast source within the set lifetime of the multicast source, it
considers that the (S, G) entry becomes invalid and the multicast source stops sending multicast
data to the multicast group.
Context
Do as follows on the PIM-IPv6 switch:
NOTE
If there is no special requirement, default values are recommended.
