The BRAS performsAAA for the host through the RADIUS server.Figure 147 Network diagramProcedure1. Configure the RADIUS server: (This section uses the Linux Free RADIUS server as anexample.)# Add BRAS IP address 4.4.4.2 and secret radius to the clients.conf file.client 4.4.4.2/32 {ipaddr = 4.4.4.2netmask=32secret=radius}# Add the username, password, and authorized IPv6 prefix to the users user information file.The username is the host MAC address, the password is radius, and the IPv6 prefix is10::10/64.000c29a6b656 Cleartext-Password :="radius"Framed-IPv6-Prefix =10::10/642.
