PIM-DM Setup
Protocol Independent Multicast-Dense Mode (PIM-DM) is used for multicast routing between
remote sites.
You can manage and configure PIM-DM routing from the PIM-DM Setup page (Network >
Configuration > IGMP). The IP Interfaces Setup table lists the existing IP interfaces on the device,
and indicates whether PIM-DM is enabled or disabled on this IP interface. From this page you can:
• View the current PIM-DM configuration for the device and the current state of PIM-DM for each IP
interface.
• Configure the global PIM-DM setup parameters for the device.
PIM-DM must be enabled on interfaces that are connected to another multicast router that separates
the device from clients using multicast traffic.
• Edit the PIM-DM configuration for an IP interface.
Note You must enable IGMP globally in order to run it on an interface.
