Now, before you can use the “Global” configuration command “aaa accounting 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 accounting multicast default” is used on a Cisco IPv6 router; to allow it to perform Authentication, Authorization, and Accounting or (AAA) accounting of IPv6 multicast services for billing and security purposes.

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

Here is the syntax of the command:

aaa accounting multicast default [start-stop | stop-only] [broadcast] [method1] [method2] [method3] [method4]

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

no aaa accounting multicast default [start-stop | stop-only] [broadcast] [method1] [method2] [method3] [method4]

The optional “start-stop” portion of the command; is used to send a “start” accounting notice at the beginning of a process and a “stop” accounting notice at the end of a process. By the way, just in case if you were wondering; the “start” accounting record is sent in the background and the requested user process begins regardless of whether the “start” accounting notice was received by the accounting (Radius) server.

The optional “stop-only” portion of the command; is used to send a “stop” accounting notice at the end of the requested user process.

Using the optional “broadcast” portion of the command; allows a router to be able to send accounting records to multiple AAA (Radius) servers. The router will simultaneously send accounting records to the first server in each group; but, if the first server is unavailable, failover occurs using the backup servers defined within that group.

Using the optional “method lists” (method1, method2, method3, and method4) with the command allows you to specify an accounting method or multiple accounting methods to be used for accounting.
