You specify an MX Series router RADIUS client for each gateway GPRS support node (GGSN), Packet Data Network Gateway (PGW), or broadband network gateway (BNG) that sends IP-based subscriber session requests and identifies the MX Series router as a RADIUS server. This task is not used for snooped accounting requests.

Before you begin to configure a RADIUS client, make sure that you have configured the interface and IP address that you want to receive RADIUS requests on the MX Series router.

To configure the RADIUS clients:

Configure the name of the RADIUS client.
```
[edit access radius]
user@host# set clients client-name 
```
Specify the IP address from which the RADIUS client sends the RADIUS requests.
```
[edit access radius]
user@host# set clients client-name address client-address  
```
Specify the MX Series router interface and IPv4 address that receive RADIUS requests from the GGSN, PGW, or BNG.
```
[edit access radius]
user@host# set clients client-name source-interface interface ipv4-address address 
```
Configure a shared secret to be used by the MX Series router and the RADIUS client for accounting.
```
[edit access radius]
user@host# set clients client-name accounting secret password  
```
(Optional) Specify that the framed-ip-address is used for subscriber creation when both the framed-route and framed-ip-address attributes are in the RADIUS accounting request from the RADIUS client. The framed-ip-netmask is also used for subscriber creation if it is in the request.
```
[edit access radius]
user@host# set clients client-name prefer-framed-ip-address 
```
By default, the framed-route attribute is used for subscriber creation when both the framed-route and framed-ip-address attributes are in the RADIUS accounting request.
(Optional) Specify that the framed-ipv6-prefix is used for subscriber creation when both the delegated-ipv6-prefix and framed-ipv6-prefix attributes are in the RADIUS accounting request from the RADIUS client.
```
[edit access radius]
user@host# set clients client-name prefer-framed-ipv6-prefix 
```
By default, the delegated-ipv6-prefix attribute is used for subscriber creation when both the delegated-ipv6-prefix and framed-ipv6-prefix attributes are in the RADIUS accounting request.
Configure the duration, in seconds, that the RADIUS response messages (sent for request messages) are stored in the MX Series router response cache before they time out.
```
[edit access radius]
user@host# set clients client-name accounting response-cache-timeout seconds 
```
Enable the RADIUS client for a specific TDF gateway.
```
[edit unified-edge gateways tdf gateway-name] 
user@host# set aaa clients client-name 
```
Use the client-name that you configured in Step 1.
