Configuration Roadmap
In a small-scale experiment network, PIM-DM is adopted to configure multicast. Enable PIM
silent on the VLANIF interfaces of SwitchA to protect SwitchA from Hello message attacks.
The configuration roadmap is as follows:
1. Enable multicast on the Switch.
2. Enable PIM-DM on each interface.
3. Enable PIM silent and configure IGMP on the VLANIF interfaces connected to hosts.
Data Preparation
To complete the configuration, you need the following data:
l Address of multicast group G: 225.1.1.1/24
l Address of multicast group S: 10.110.5.100/24
l Version of the IGMP protocol running between routers and hosts: IGMPv2
NOTE
This configuration example describes only the commands used to configure PIM-DM.
