1. Connect to the router's CLI (Command Line Interface).
2. Enter global configuration mode by typing enable and then configure terminal.
3. Specify the IP address of the RADIUS server using the radius-server host command. For example, radius-server host 192.168.1.100.
4. Set the shared secret or password for the RADIUS server using the radius-server key command. For example, radius-server key mypassword.
