Chapter 3 Configuring the Cisco 1604 Router Overview of Steps Overview of Steps After you verify your start up configuration, follow these steps to configure the router: Step 1—Configuring the Host Name, Password, and Time Stamps Step 2—Configuring Local AAA Security Step 3—Configuring the Ethernet Interface Step 4—Configuring Basic Rate Interface Step 5—Configuring Dial-on-Demand Routing Step 6—Testing the Cisco 1604 Connection to the Cisco AS5300 Step 7—Confirming the Cisco 1604 Final Running Configura
Chapter 3 Configuring the Cisco 1604 Router Step 1—Configuring the Host Name, Password, and Time Stamps cisco 1604 (68360) processor (revision C) with 17920K/512K bytes of memory. Processor board ID 08823977, with hardware revision 00972006 Bridging software. X.25 software, Version 3.0.0. Basic Rate ISDN software, Version 1.1. 1 Ethernet/IEEE 802.
Chapter 3 Configuring the Cisco 1604 Router Verifying Host Name, Password, and Time Stamp Configuration To configure the host name, password and timestamps for the Cisco 1604, enter the following commands beginning in user EXEC mode: Step 1 Enter privileged EXEC mode. Router> enable Step 2 Enter global configuration mode. Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Step 3 Assign a host name to the router.
Chapter 3 Configuring the Cisco 1604 Router Step 2—Configuring Local AAA Security interface Serial0 no ip address shutdown ! interface BRI0 no ip address shutdown ! ip classless ! ! line con 0 line vty 0 4 login ! Step 2 Log in with your new enable password. Step 3 Exit out of enable mode by using the disable command. The prompt changes from robo-austin# to robo-austin>. Step 4 Enter the enable command followed by your password.
Chapter 3 Configuring the Cisco 1604 Router Verifying Local AAA Security Configuration To configure local AAA security on the Cisco 1604, enter the following commands beginning in global configuration mode: Step 1 Create a local username for yourself. Make sure to change “joe-admin” to your own username and “joe-password” to your own password. This step prevents you from getting locked out of the router when you enable AAA.
Chapter 3 Configuring the Cisco 1604 Router Step 3—Configuring the Ethernet Interface Step 3 Enter the show running command to see the Cisco 1604’s current configuration: robo-austin# show running Building configuration... Current configuration: ! version 12.
Chapter 3 Configuring the Cisco 1604 Router Verifying the Ethernet Interface Configuration Step 2 Bring up the interface. This command changes the state of the interface from administratively down to up. robo-austin(config-if)# no shutdown Verifying the Ethernet Interface Configuration To verify the Cisco 1604’s Ethernet interface configuration: Step 1 Enter the show ip interface brief command, which enables you to quickly check the status of all router interfaces.
Chapter 3 Configuring the Cisco 1604 Router Verifying the Ethernet Interface Configuration Step 3 Establish connectivity with an Ethernet-based device. In this example, IP address 10.1.4.2 is assigned to the first external PC on this LAN to test for router-to-PC connectivity. The PC’s DOS prompt application is opened and the ping 10.1.4.1 command is issued. Microsoft(R) Windows 95 (C)Copyright Microsoft Corp 1981-1996. C:\WINDOWS> ping 10.1.4.1 Pinging 10.1.4.
Chapter 3 Configuring the Cisco 1604 Router Step 4—Configuring Basic Rate Interface Step 4—Configuring Basic Rate Interface Enable the Cisco 1604’s Basic Rate Interface (BRI) connectivity with the telephone company’s central office switch. PPP framing is used on the B channels. You can authenticate the remote side on any connection.
Chapter 3 Configuring the Cisco 1604 Router Verifying BRI Configuration Verifying BRI Configuration Step 1 Enter the no shutdown command.
Chapter 3 Configuring the Cisco 1604 Router Step 5—Configuring Dial-on-Demand Routing Step 3 Enter the show ip interface brief command to check the current state of the interface: robo-austin# show ip interface brief Interface IP-Address BRI0 10.1.254.4 BRI0:1 unassigned BRI0:2 unassigned Ethernet0 10.1.4.
Chapter 3 Configuring the Cisco 1604 Router Verifying DDR Configuration Step 6 Build a dialer map that maps to the Cisco AS5300’s IP address, host name, and directory number. The static route in Step 8 points to this dialer map. robo-austin(config-if)# dialer map ip 10.1.254.1 name hq-sanjose 14085551234 robo-austin(config-if)# exit Step 7 Define a DDR’s dialer-list to allow any IP packets to establish and maintain calls.
Chapter 3 Configuring the Cisco 1604 Router Verifying DDR Configuration Step 2 Enter the show dialer command. The following example shows that the Cisco 1604 has not placed any calls yet, and there have been no failures. An ISDN interface is a dialer interface. Key statistics are shown for each B channel: robo-austin# show dialer BRI0 - dialer type = ISDN Dial String Successes Failures Last called 14085551234 0 0 never 0 incoming call(s) have been screened. 0 incoming call(s) rejected for callback.
