Remote Access Configuration Tasks

Before you begin to configure B-RAS, you need to collect the following information for the RADIUS authentication and accounting servers:

• IP addresses
• User Datagram Protocol (UDP) port numbers
• Secret keys

Each configuration task is presented in a separate section in this chapter. Most of the B-RAS configuration tasks are optional.

To configure B-RAS, perform the following tasks:

1. Configure a B-RAS license.
2. (Optional) Map a user domain name to a virtual router. By default, all requests go through a default router.
3. (Optional) Set up domain name and realm name usage.
4. (Optional) Specify a single name for users from a domain.
5. Configure an authentication server on the router.
6. (Optional) Configure UDP checksums.
7. (Optional) Configure an accounting server on the router.
8. (Optional) Configure Domain Name System (DNS) and Windows Internet Name Service (WINS) name server addresses.
9. (Optional) Configure a local address pool for remote clients.
10. (Optional) Configure one or more DHCP servers.
11. Create a PPP interface on which the router can dynamically create an IP interface.
12. (Optional) Configure AAA profiles.
13. (Optional) Use vendor-specific attributes (VSAs) for Dynamic Interfaces.
14. (Optional) Set idle or session timeout.
15. (Optional) Limit the number of active subscribers on a virtual router (VR) or port.
16. (Optional) Set up the router to notify RADIUS when a user fails AAA.
17. (Optional) Configure a RADIUS download server on the router.
18. (Optional) Configure the Session and Resource Control (SRC) client (formerly the SDX client).
19. (Optional) Set baselines for AAA statistics or RADIUS authentication and accounting statistics.
