Duplicate and Broadcast Accounting

Normally, the JUNOSe software sends subscriber-related AAA accounting information to the virtual router that authenticates the subscriber. If an operational virtual router is configured that is different from the authentication router, it also receives the accounting information. You can optionally configure duplicate or broadcast AAA accounting, which sends the accounting information to additional virtual routers simultaneously. The accounting information continues to be sent to the authenticating virtual router, but not to the operational virtual router.

Both the duplicate and broadcast accounting features are supported on a per-virtual router context, and enable you to specify particular accounting servers that you want to receive the accounting information.

For example, you might use broadcast accounting to send accounting information to a group of your private accounting servers. Or you might use duplicate accounting to send the accounting information to a customer’s accounting server.

• Duplicate accounting—Sends the accounting information to a particular virtual router
• Broadcast accounting—Sends the accounting information to a group of virtual routers. An accounting virtual router group can contain up to four virtual routers and the E-series router supports a maximum of 100 virtual router groups. The accounting information continues to be sent to the duplicate accounting virtual router, if one is configured.
