Configuration Roadmap
In a small-scale experiment network, PIM-DM is adopted to configure multicast. Enable PIM
silent on the VLANIF interfaces of Switch A to protect Switch A from Hello message attacks.
The configuration roadmap is as follows:

Procedure
Step 1 Configure the IP address of each interface and the unicast routing protocol.
# Configure IP addresses and masks of interfaces on the switches according to
Configure OSPF between switches to ensure that the switches can communicate at the network
layer and update routes through the unicast routing protocol.
For details on how to configure IP addresses of interfaces, see Configuring IP Addresses for
Interfaces in the Quidway S3700 Series Ethernet Switches Configuration Guide - Basic
Configuration. For details on how to configure OSPF, see OSPF Configuration in the Quidway
S3700 Series Ethernet Switches Configuration Guide - IP Routing.
Step 2 Enable multicast on all switches and enable PIM-DM on all interfaces.
# Enable multicast on Switch A and enable PIM-DM on each interface. The configurations of
Switch B, Switch C, and Switch D are similar to the configuration of Switch A, and are not
provided here.
[SwitchA] multicast routing-enable
[SwitchA] interface vlanif 100
[SwitchA-Vlanif100] pim dm
[SwitchA-Vlanif100] quit
[SwitchA] interface vlanif 101

Configure the IP addresses of interfaces and the unicast routing protocol. PIM is an intra-
domain multicast routing protocol that depends on a unicast routing protocol. The multicast
routing protocol can work normally after the unicast routing protocol works normally.
Enable multicast on the switch.
Enable PIM-DM on each interface.
Address of multicast group G: 225.1.1.1/24
Address of multicast group S: 10.110.5.100/24
Version of the IGMP protocol running between routers and hosts: IGMPv2
