Cisco Ccna (640-553) Security Exam Training: Using The Aaa Route Download Command

In today’s article, I’m going to quickly inform you about the Cisco IOS global configuration mode command named “aaa route download”.

CCNA’s (like you) use the “aaa route download” command, on a router to “enable” the static route download feature and to set the amount of time between downloads.

Another way of saying it is, network administrators use the command, to tell a router to begin downloading static route information from an AAA server; the only major requirement when using this command is that the router must have the name “hostname”.

Because when the router, is actually communicating with an AAA server it introduces itself as “hostname”. (hostname -1, hostname -2, hostname -3 etc…).

When a router begins downloading static routes, it won’t stop; until it fails an index and no more routes can be downloaded.

Below is the command’s syntax:

aaa route download [time] [authorization method-list]

As you can see, the command uses the time argument; this (optional) argument is used to indicate the time between downloads in minutes. The range is from 1 to 1440 minutes.

Note: If you don’t specify a time, the default time between downloads will be 720 minutes.

And, the “authorization” keyword with the method-list argument are both optional as well; they are used to specify a named method list to which RADIUS authorization requests for static route downloads are sent. If these attributes are not set, all RADIUS authorization requests will be sent to the servers that are specified by the default method list.

Below is an example of the command being used:

Router>enable
Router#configure terminal
Router(config)#aaa new-model
Router(config)#aaa route download 90
Router(config)#exit
Router#

In the example above, the time between downloads is being set to 90 minutes.

And, just like mostly all Cisco IOS commands; you can use the word “no” in front of the command to remove (disable) the configured command; like you see below:

Router(config)#no aaa route download 90

By the way, if you decide to use the command, make sure your router(s) is running Cisco IOS 12.2(8)T or higher.

I hope this article was very informative and helped you quickly understand the usage of the aaa route download command. If you need to learn more; I suggest you visit my website, were you’ll find the latest information regarding the Cisco CCNA (640-553) Security exam techniques.

To your success,
