======RADIUS integration of SSG BRAS with Nokia BNG (AUTH/ACCT)======
=====Assignment=====
Radius contains a specification for what data should be present in request and response packets, but allows you to extend its functionality to a specific case by using Vendor Specific Attribute - attributes that are specified by a particular vendor. For example, to transmit information that has a non-standard display. In this case it is necessary for Nokia BNG to understand attributes from SSG BRAS and vice versa (SSG BRAS is a Radius client, Nokia BNG is a Radius server), for this purpose FreeRadius package has a possibility to work out attributes on the fly, which pass through it both in one and in the other direction.

=====Configuring FreeRADIUS as a balancing proxy VASE NAS adapter for Nokia AAA=====
{{ :dpi:dpi_components:radius:radius_integration:vase_to_nokia.tar.gz |}}

The attached archive contains the folders:
  - ''scripts'' - scripts of VASE NAS requests emulation for debugging and testing. The scripts contain examples of authorization and account requests for test users.
  - ''proxy/raddb'' - FreeRADIUS configuration of VASE NAS adaptation for Nokia AAA.

<note tip>Adaptation of AUTH and ACCT queries has been implemented, plans to add COA.</note>

To deploy in a production environment, you need to:
  - Install the FreeRADIUS server according to [[https://freeradius.org/documentation/|installation instructions]] on the software website.
  - Replace the default configuration created by the installer with the configuration from the archive.
  - Configure addresses of VASE NAS source clients and Nokia AAA target servers according to [[dpi:dpi_components:radius:balancing_proxy]] instructions.
  - Configure the source realm for VASE NAS users in the ''proxy.conf'' file (currently ''beelinerouter'' and ''beelinerouter-iptv'').
  - Configure adapter settings in the ''vase_to_nokia {}'' section in the ''radiusd.conf'' file:
    * ''nokia_realm'' - target realm for Nokia AAA users;
    * ''nokia_iptv_realm'' - target realm for Nokia AAA IP-TV users;
    * ''nas_identifier'' - NAS identifier for Nokia AAA users;
    * ''nas_port_type'' - port type for Nokia AAA;
    * ''nas_port_id'' - port identifier for Nokia AAA.

Example setting:
<code bash>
vase_to_nokia {
    nokia_realm = "MSFT 5.0"
    nokia_iptv_realm = "MSFT_IPTV"

    nas_identifier = "bras904.krasnodar"
    nas_port_type = ethernet
    nas_port_id = "lag-2:3330.3330"
}

''server1/raddb'' - FreeRADIUS configuration of Nokia AAA emulator #1.\\
''server2/raddb'' - FreeRADIUS configuration of Nokia AAA emulator #2.\\
These emulator configurations contain test user sets and target realm settings.
