Configuring a Dynamic Profile for Client Access
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:
- Create a basic dynamic profile.
- Configure the necessary router interfaces that
you want accessing DHCP clients to use.
See Subscriber Interface Overview for information about the types of interfaces you can use with dynamic profiles and how to configure them.
- 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.
- Configure all RADIUS values that you want the profiles
to use when validating DHCP clients for access to the multicast network.
See Configuring RADIUS Server Parameters for Subscriber Access
To configure an initial client access dynamic profile:
- Access an IGMP access profile.
- 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.
- (Optional) Enable accounting on the IGMP interface.
- Set the IGMP interface to remain enabled.
- [edit dynamic-profiles access-profile protocols igmp interface $junos-underlying-interface]
- user@host# set disable:$junos-igmp-enable

Note: RADIUS is capable of disabling IGMP. By assigning the enable variable to the disable statement, you can ensure that IGMP remains enabled.
- (Optional) Specify a group policy for the IGMP interface.
- (Optional) Enable immediate leave on the IGMP interface.
- (Optional) Disable the collection of IGMP join and leave even statistics on the IGMP interface.
- (Optional) Set the IGMP interface to obtain the IGMP version from RADIUS.
