Learning by Doing: CISCO Certified Network ... - SCN Research

Step-By-Step Instructions:
1. Configure the basics on each router. Don’t forget the loop back adapters. Set up
and cable the lab as shown. Pick a routing protocol to use and advertise the
networks.
2. Set the ISDN switch type on geoffrey and osowski routers:
geoffrey(config)# isdn switch-type basic-ni
geoffrey(config)#dialer-list 1 protocol ip permit
osowski(config)# isdn switch-type basic-ni
osowski(config)#dialer-list 1 protocol ip permit
3. Configure the ISDN interface on “smarts.” We will start by getting two of them
up first. You will be configuring the ip address, the isdn spid (service profile
identifiers), and a dialer map (how to get from here to there).
geoffrey(config)#int bri0/0
geoffrey(config-if)#ip address 192.168.1.1 255.255.255.0
geoffrey(config-if)#no shut
geoffrey(config-if)#dialer-group 1
geoffrey(config-if)#dialer map ip 192.168.1.2 name osowski 5554000
geoffrey(config-if)#isdn spid1 51055512340001 5551234
geoffrey(config-if)#isdn spid2 51055512350001 5551235
geoffrey(config-if)#enc ppp
geoffrey(config-if)#ppp authentication chap
geoffrey(config)#username osowski password cisco
geoffrey(config)#ip host osowski 192.168.1.2
osowski(config)#int bri0/0
osowski(config-if)#ip address 192.168.1.1 255.255.255.0
osowski(config-if)#no shut
osowski(config-if)#dialer-group 1
osowski(config-if)#dialer map ip 192.168.1.2 name geoffrey 5551234
osowski(config-if)#isdn spid1 51055540000001 5554000
osowski(config-if)#isdn spid2 51055540010001 5554001
osowski(config-if)#enc ppp
osowski(config-if)#ppp authentication chap
osowski(config)#username geoffrey password cisco
osowski (config)#ip host geoffrey 192.168.1.2
4. Try to ping the loopback. You should not be able to see it. It should not have
shown up in the ip routing table either. The ISDN line comes up, stays active,
and then shuts off pretty quickly. It’s actually faster than the routing protocol (I
used EIGRP). In order to make this work we need to set up some static routes
between the two.
