Configuring the Router to Work with the SRC Software

E Series Broadband Services Routers have an embedded SRC client that interacts with the SRC software. For information about configuring the SRC client, see SRC Client Configuration Overview.

Figure 2 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.

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 10.10.1.1 255.255.255.255 host1(config-if)#ip address 10.10.2.1 255.255.255.255 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 enable host1(config)#sscc retryTimer 200 host1(config)#sscc primary address 10.10.1.2 port 3288
