In a PIM-SM network, the DR directly connected to the multicast source encapsulates multicast
data in a Register message and sends the message to the RP in unicast mode. The RP then
decapsulates the message, and forwards the multicast data to receivers along the RPT.
13.8 Adjusting Control Parameters for Forwarding
A multicast device sends Join messages upstream to require forwarding multicast data and Prune
messages to require stopping the forwarding of multicast data. You can adjust control parameters
for multicast data forwarding as required. If there is no special requirement, adopt default values.
13.9 Configuring Control Parameters for Assert
If a multicast device can receive multicast data through the downstream interface, this indicates
that other upstream devices exist in this network segment. The device then sends an Assert
message through the downstream interface to take part in the election of the unique upstream
device.
13.10 Adjusting Control Parameters for the SPT Switchover
A high volume of multicast data traffic increases the load of an RP, and may result in a fault.
To solve this problem, IPv6 PIM-SM allows the RP or the DR at the group member side to
trigger the SPT switchover when the rate of multicast packets is high.
13.11 Configuring PIM GR (IPv6)
In an IPv6 PIM-SM network, PIM GR can be applied to a device with dual main control boards
to ensure normal multicast data forwarding during master-slave switchover.
13.12 Configuring PIM-IPv6 Silent
The interface directly connecting a multicast device to a user host needs to be enabled with PIM.
In this case, some malicious hosts may simulate a large number of PIM Hello messages and send
the messages to the interface for processing. As a result, the multicast device is suspended. To
avoid the preceding case, you can set the interface to be in the PIM Silent state.
13.13 Maintaining PIM-SM
Maintaining IPv6 PIM-SM involves resetting PIM statistics, and monitoring PIM running status.
13.14 Configuration Example
Configuration examples are provided to show how to construct a basic IPv6 PIM-SM network.
