Configuring IP-Based TDF Subscriber Setup When MX Series Router Is a RADIUS Server

This task describes how to configure IP-based TDF subscriber setup when the gateway GPRS support node (GGSN), Packet Data Network Gateway (PGW), or broadband network gateway (BNG) identifies the MX Series router as a RADIUS server. An IP-based TDF subscriber is defined by the AVP values in the RADIUS accounting request received.

Before you configure the subscriber setup, you must do the following:

  • Configure the access interfaces on the MX Series router chassis.

  • Configure the PCEF profile.

  • Configure the interface and IP address that you want to receive RADIUS requests on the MX Series router.

  • Configure a TDF gateway.

To configure IP-based subscriber setup when the MX Series router acts as a RADIUS server:

  1. Configure the TDF interfaces that can be used by TDF subscribers.

    See Configuring a TDF Logical Interface.

  2. Associate the TDF interface to an access interface in a VRF routing instance.

    See Configuring TDF Interface to Access Interface Associations in VRFs.

  3. Configure sets of source IP addresses that TDF domains can use to accept traffic.

    See Configuring Address Pools for Source-IP Filtering of IP-Based Subscribers.

  4. Configure TDF domains that can be assigned to subscribers.

    See Configuring a Set of IP-Based TDF Subscriber Properties with a TDF Domain.

  5. Configure RADIUS clients that can send the subscriber accounting requests.

    See Configuring RADIUS Clients That Send Accounting Requests for IP-Based Subscribers.

  6. Configure how Junos OS selects TDF domains and PCEF profiles for subscribers.

    See Configuring Assignment of TDF Subscriber Properties and Policy-Control Properties to IP-Based Subscribers.
