Prerequisites for RADIUS Route Download

AAA network security must be enabled before you perform the tasks in this feature.

Information About RADIUS Route Download

The RADIUS Route Download feature allows users to configure their network access server (NAS) to direct RADIUS authorization. Users configure a separate named method list (in addition to the default method list) for static route download requests sent by their NAS to authorization, authentication, and accounting (AAA) servers.

Before this feature, RADIUS authorization for static route download requests was sent only to AAA servers specified by the default method list.

This feature extends the functionality of the aaa route download command to allow users to specify the name of the method list that will be used to direct static route download requests to the AAA servers. The aaa route download command may be used to specify a separate method list for downloading static routes. This method list can be added by using the aaa authorization configuration command.

How to Configure RADIUS Route Download

Use the following sections to configure the RADIUS Route Download feature.

•Configuring RADIUS Route Download

•Verifying RADIUS Route Download

Configuring RADIUS Route Download

To configure the NAS to send static route download requests to the servers specified by a named method list, use the following commands in global configuration mode:

 
Command
Purpose

Step 1 

Router(config)# aaa authorization configuration method-name [radius | tacacs+ | group group-name]

Downloads static route configuration information from the AAA server using RADIUS.

Step 2 

Router(config)# aaa route download [time] [authorization method-list]

Enables the static route download feature. Use the authorization method-list attributes to specify a named method list to which RADIUS authorization requests for static route downloads are sent.

Verifying RADIUS Route Download

To verify the routes that are installed, use the show ip route command in EXEC mode.

To display information that is associated with RADIUS, use the debug radius command in privileged EXEC mode.

Configuration Examples

This section provides the following configuration examples:
