Configuring the Router to Work with the SRC Software

E-series routers have an embedded SRC client that interacts with the SRC software. For information about configuring the SRC client, see Configuring the SRC Client.

Configuration Example

Figure 12 shows the scenario for this example. Subscribers obtain access to ISP Boston via a router. Subscribers log in through the SRC software, and a RADIUS server provides authentication.

Figure 12: Non-PPP Equal-Access Configuration Example

The following steps describe how to configure this scenario.

1. Configure interfaces on the router.

   host1(config)#interface loopback 0

   host1(config-if)#ip address 10.10.1.1 255.255.255.0

   host1(config-if)#ip address 10.10.2.1 255.255.255.0 secondary

   host1(config-if)#exit

   host1(config)#interface fastEthernet 2/0

   host1(config-if)#ip unnumbered loopback 0

2. Configure the parameters to enable the router to forward authentication requests to the RADIUS server.

   host1(config)#radius authentication server 10.10.1.2

   host1(config)#udp-port 1645

   host1(config)#key radius

3. Specify the authentication method.

   host1(config)#aaa authentication ppp default radius

   Or

   host1(config)#aaa authentication ppp default none

4. Enable the DHCP local server.

   host1(config)#service dhcp-local

5. Specify the IP addresses that are in use, so that the DHCP local server cannot assign these addresses.

   host1(config)#ip dhcp-local excluded-address 10.10.1.1

   host1(config)#ip dhcp-local excluded-address 10.10.1.2

6. Configure the DHCP local server to provide IP addresses to subscribers of ISP Boston.

   host1(config)ip dhcp-local pool ispBoston

   host1(config-dhcp-local)#network 10.10.2.0 255.255.255.0

   host1(config-dhcp-local)#domain-name ispBoston

   host1(config-dhcp-local)#default-router 10.10.2.1

   host1(config-dhcp-local)#lease 0 0 10

   host1(config-dhcp-local)#ip dhcp-local limit atm 5

7. Configure the SRC client.

   host1(config)#sscc primary address 10.10.1.2 port 3310

   host1(config)#sscc enable

   host1(config)#sscc retryTimer 200
