Configuration prerequisites and guidelines
Configure IP addresses for the router and servers as shown in
•
router, and servers can reach each other.
Configure the RADIUS server correctly to provide authentication and accounting functions.
•
For re-DHCP portal authentication, configure a public address pool (20.20.20.0/24) and a private
•
address pool (10.0.0.0/24) on the DHCP server. (Details not shown.)
• For re-DHCP portal authentication, the router must be configured as a DHCP relay agent and the
portal-enabled interface must be configured with a primary IP address (a public IP address) and a
secondary IP address (a private IP address). For information about DHCP relay agent configuration,
see Layer 3—IP Services Configuration Guide.
Make sure the IP address of the portal device added on the portal server is the public IP address
•
(20.20.20.1) of the router's interface connecting the host. The private IP address range for the IP
address group associated with the portal device is the private subnet 10.0.0.0/24 where the host
resides. The public IP address range for the IP address group is the public subnet 20.20.20.0/24.
Configuration procedure
Perform the following configurations on the router.
1. Configure a RADIUS scheme:
# Create a RADIUS scheme named rs1 and enter its view.
<Router> system-view
[Router] radius scheme rs1
# Specify the primary authentication server and primary accounting server, and configure the keys
for communication with the servers.
[Router-radius-rs1] primary authentication 192.168.0.113
[Router-radius-rs1] primary accounting 192.168.0.113
[Router-radius-rs1] key authentication simple radius
[Router-radius-rs1] key accounting simple radius
[Router-radius-rs1] user-name-format without-domain
# Specify the security policy server.
[Router-radius-rs1] security-policy-server 192.168.0.114
