, three hosts access the BRAS as subnet-leased users. The BRAS performs
AAA for the hosts through the RADIUS server.
Figure 149 Network diagram
Procedure
1.
Configure the RADIUS server: (This section uses the Linux Free RADIUS server as an
example.)
# Add BRAS IP address
4.4.4.2
and secret
radius
to the
clients.conf
file.
client 4.4.4.2/32 {
ipaddr = 4.4.4.2
netmask=32
secret=radius
}
