On the Multicast Routing (PIM-SM) > Interfaces tab you can define over which interfaces of Sophos UTM multicast communication should take place.

To create a new PIM-SM interface, do the following:

  1. On the Interfaces tab, click New PIM-SM Interface.

    The dialog box Add PIM-SM Interface opens.

  2. Specify the following settings:

    Name: Enter a descriptive name for PIM-SM interface.

    Interface: Select an interface that is to accept PIM and IGMP network traffic.

    DR priority (optional): Enter a number that defines the designated router (DR) priority for the interface. The router with the highest priority honors IGMP requests if more than one PIM-SM routers are present on the same network segment. Numbers from 0 to 232 are possible. If you do not provide a priority, 0 is used by default.

    IGMP: Select the version of the Internet Group Management Protocol that is to be supported. IGMP is used by recipients to establish multicast group memberships.

    Comment (optional): Add a description or other information.

  3. Click Save.

    The new PIM-SM interface is added to the interfaces list.

To either edit or delete a PIM-SM interface, click the corresponding buttons.
