Ipv6 Cisco Training: Using The “aaa Authorization Multicast Default” Command

Now, before you can use the “Global” configuration command “aaa authorization multicast default” on your Cisco IPv6 router. The following conditions must be met:


• Your network must be running both IP protocols (IPv4 and IPv6).

• Your network must be running (configured for) IPv6 multicast services.

• Your network must have a “Radius” server with an IPv4 address assigned to it.

• Your Cisco router must be running Cisco IOS 12.4(4)T or higher.

The “Global” configuration command “aaa authorization multicast default” is used on a Cisco IPv6 router; to allow it to perform Authentication, Authorization, and Accounting authorization or (AAA) authorization. In other words, you can use the “aaa authorization multicast default” command to activate AAA authorization and set the method (parameters) in which a Cisco IPv6 router will restrict user access to an IPv6 multicast network.

By default, Cisco (IPv6) routers are not enabled to perform (AAA) authorization for an IPv6 multicast network; that’s why you must type the “aaa authorization multicast default” command while the router is in “Global” configuration mode.

Here is the syntax of the command:

aaa authorization multicast default [method3 | method4]

If you need to disable AAA authorization on a Cisco IPv6 router, all you need to do is type the word “no” in front of the command like this:

no aaa authorization multicast default [method3 | method4]

The optional “method lists” (method3 or method4) portion of the command; is used to specify an authorization method or methods that can be used for authorization. Currently, the Cisco IOS IPv6 software supports the following methods for authorization:

1. group radius
2. group group-name
3. if-authenticated
4. local
5. none

I would like to explain each of these five authorization methods in more detail, but that would make this article very lengthy, so I’ll just save that information for a future article.

So, until next time; I invite you to visit my website were you’ll find the latest information regarding Cisco IPv6 Design and Implementation Techniques and also get the complete information on how to use the “aaa authorization multicast default” global configuration command in your IPv6 network environment.

To your success,
