# Add BRAS IP address
4.4.4.2
and secret
radius
to the
clients.conf

client 4.4.4.2/32 {
ipaddr = 4.4.4.2
netmask=32
secret=radius
}
# Add the usernames and passwords to the

.
2.2.2.2 Cleartext-Password :="radius"
2.2.2.3 Cleartext-Password :="radius"
2.2.2.4 Cleartext-Password :="radius"
2.
Configure the BRAS:
a.
Configure IP addresses for interfaces. (Details not shown.)

Configure a RADIUS scheme:
# Create a RADIUS scheme named

<Device> system-view
[Device] radius scheme rs1
# Configure primary servers and keys for authentication and accounting.
[Device-radius-rs1] primary authentication 4.4.4.1
[Device-radius-rs1] primary accounting 4.4.4.1
[Device-radius-rs1] key authentication simple radius
[Device-radius-rs1] key accounting simple radius
# Exclude the ISP name from the username sent to the RADIUS server.
[Device-radius-rs1] user-name-format without-domain
[Device-radius-rs1] quit
c.
Configure the ISP domain:
# Create an ISP domain named
dm1
and enter its view.
[Device] domain dm1
# Configure
dm1
to use RADIUS scheme
rs1.
[Device-isp-dm1] authentication ipoe radius-scheme rs1
[Device-isp-dm1] authorization ipoe radius-scheme rs1
[Device-isp-dm1] accounting ipoe radius-scheme rs1
