Configuring Basic Pim-Dm Functions; Establishing The Configuration Task; Enabling Ipv4 Multicast Routing - Huawei Quidway s3700 series Configuration Manual

Configuration Guide - Multicast
Adjusting Control Parameters for Assert
You can set the period for a switch to retain the Assert state. The switch that fails in the election
prevents the downstream interface from forwarding multicast data during this period. After the
period expires, the downstream interface continues to forward multicast data.
Attack Defense Using PIM Silent
Some hosts may send a large number of malicious PIM Hello messages, which results in the
suspension of the switch. The PIM Silent function can then be configured on the interfaces
connected to hosts to protect the switch.

6.3 Configuring Basic PIM-DM Functions

Ensure that unicast routes are reachable before enabling IPv4 multicast routing, and enable PIM-
DM on each interface of the multicast device. In this manner, the PIM-DM network can work
normally.

6.3.1 Establishing the Configuration Task

Before configuring basic PIM-DM functions, configure a unicast IPv4 routing protocol.
Applicable Environment
PIM-DM is applicable to a small-scale network, and most network segments of the network have
receivers.
Pre-configuration Tasks
Before configuring basic PIM-DM functions, complete the following configuration tasks:
l
Data Preparation
To configure basic PIM-DM functions, you need the following data.
No.

6.3.2 Enabling IPv4 Multicast Routing

Prior to configuring all IPv4 multicast features, enable IPv4 multicast routing.
