Figure 8-11 Configure Layer 3 portal authentication
Configuration procedure
z Make sure that the IP address of the portal device added on the portal server is the IP
address of the interface connecting users (20.20.20.1 in this example), and the IP address
group associated with the portal device is the network segment where the users reside
(8.8.8.0/24 in this example).
z You need to configure IP addresses for the devices as shown in Figure 8-11 and ensure
that routes are available between devices.
z Perform configurations on the RADIUS server to ensure that the user authentication and
accounting functions can work normally.
