Example: Configuring the SRC 3GPP Gateway

 

This example describes how to configure the SRC 3GPP gateway.

Requirements

This example uses the following hardware and software components:

  • One or more C Series Controllers running the Juniper Networks Session and Resource Control (SRC) software

  • One or more MX Series 3D Universal Edge Routers or E Series Broadband Services Routers

  • One PCRF

  • Junos OS Release 11.4 or later

No special configuration beyond device initialization is required before you can configure this feature.

Before you configure and apply the configurations in this example, be sure you have an understanding of the following:

  • SRC 3GPP gateway

  • Diameter

  • SAE

Overview

This example does not show all possible configuration choices.

Topology

This example shows how to configure the SRC software for the SRC 3GPP gateway component. The SRC 3GPP gateway is connected to a single PCRF over the Gx interface running the Diameter application. The C Series Controller is also connected to an MX Series router called mx1. In this example, the connection to the mx1 router is using the Junos OS device driver.

This example does not show all possible configuration choices.

Configuration

To configure the SRC 3GPP gateway, perform these tasks:

CLI Quick Configuration

To quickly configure this example, copy the following commands, paste them in a text file, remove any line breaks, change any details necessary to match your network configuration, and then copy and paste the commands into the CLI at the [edit] hierarchy level.

Configure the Local Properties for the SRC 3GPP Gateway

Step-by-Step Procedure

Local properties for the SRC 3GPP gateway include the Gx interface, the connection to the Juniper Networks database directory, the directory-monitoring properties, logging, specifying which group configuration to use for the SRC 3GPP gateway, and configuring the NIC operating properties.

  1. Configure the directory-connection properties for the SRC 3GPP gateway.
  2. Configure directory-eventing.
  3. Configure the SRC 3GPP gateway Gx interface:
  4. Configure logging.
  5. Specify the shared group for the local configuration.
  6. Configure the NIC operating properties:

Results

Confirm the local configuration properties. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

Configure the Shared Properties for the SRC 3GPP Gateway

Step-by-Step Procedure

Configure the shared properties for the SRC 3GPP gateway including the shared group configuration, NIC proxy configuration, and subscriber type.

  1. Specify the group to configure:
  2. Configure the NIC proxy configuration:
  3. Configure the subscriber type:

Results

Confirm the shared configuration properties. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

Adding the PCRF as a Diameter Peer

Step-by-Step Procedure

You must specify the PCRF as a Diameter peer. This example uses a single PCRF, which connects to the C Series Controller over the SRC 3GPP gateway Gx interface using the Diameter application.

  1. To add the PCRF as a Diameter peer:

Results

From configuration mode, confirm the configuration for the PCRFs. If the output does not display the intended configuration, repeat the configuration instructions in this example to correct it.

Add the MX Series Router as a Shared Network Device.

Step-by-Step Procedure

Add the MX Series router as a shared network device using the Junos OS device driver.

  1. Add the MX Series router as a shared network device.
  2. Configure the SAE to manage the MX Series router.
