Configuring Dynamic DHCP Client Access to a Multicast Network

This topic describes how to create a basic dynamic profile that enables DHCP clients to dynamically access the multicast network.

Before you configure dynamic profiles for initial client access:

  1. Create a basic dynamic profile.

    See Configuring a Basic Dynamic Profile.

  2. Configure the necessary router interfaces that you want accessing DHCP clients to use.

    See DHCP Subscriber Interface Overview for information about the types of interfaces you can use with dynamic profiles and how to configure them.

  3. Ensure that the router is configured to enable communication between the client and the RADIUS server.

    See Specifying the Authentication and Accounting Methods for Subscriber Access.

  4. Configure all RADIUS values that you want the profiles to use when validating DHCP clients for access to the multicast network.

    See RADIUS Servers and Parameters for Subscriber Access

To configure an initial client access dynamic profile:

  1. Access an IGMP access profile.
  2. Define the IGMP interface with the interface variable.
    Note:

    The variable value is replaced by the name of the interface over which the router received the DHCP message.

  3. (Optional) Enable or disable accounting on the IGMP interface.

    or

    Note:

    This statement enables you to override the accounting setting at the IGMP protocol level. For example, if IGMP accounting is enabled at the [edit protocols igmp interface interface-name] hierarchy level, you can use the no-accounting statement to disable accounting for any IGMP interfaces that are dynamically created by the dynamic profile. If IGMP accounting is not enabled at the [edit protocols igmp interface interface-name] hierarchy level, you can use the accounting statement to enable accounting for any IGMP interfaces that are dynamically created by the dynamic profile.

  4. Set the IGMP interface to remain enabled.
    Note:

    RADIUS is capable of disabling IGMP. By assigning the enable variable to the disable statement, you can ensure that IGMP remains enabled.

  5. (Optional) Specify a group policy for the IGMP interface.
  6. (Optional) Enable immediate leave on the IGMP interface.
  7. (Optional) Set the IGMP interface to obtain the IGMP version from RADIUS.
