1. Comm server ( 1 point) 2. Diagram (1)
Include ip address, area number, interface, make your diagram update. Remember to mark FRSW’s interface number too, you will need it on troubleshooting.

3 Physical connection (1) 4. cat3550 setup (1)

5 cat5 address (1)
sc0 address on VLANA, 135.x.30.30/22, where x is the rack number, make it be reached by your topology

6. IRDP (2)
Vlana’s host use irdp, male R6 most preferred and R3 least preferred. ip irdp preference 100

7. Framerelay (2)
28 bits subnet. Only use the dlci showed on the given diagram (hub & spoke, not fully meshed). no frame-relay inverse-arp frame map ip …

8. Loopback address (1)
All of the routers has loopback interface. 135.y.x.x, where y is the rack num. And x is the router num.

9. Address (1)
vlana: /22; vlanb: /26; framerelay int: /28; isdn: /30; others: /24 use 135.x.0.0 to setup all interfaces except explicitly asked. e0/0 o R1 is 150.100.1.x (BB1); e0/0 on R4 is 150.100.2.x (BB2).

10. OSPF (3)
Frame relay cloud on area 1, vlana on area 0, R2’s ring on area 2, vlanb on area 5, isdn on area 6.

Make loopbacks on existing area.

11. OSPF cost (2)
Change the ospf cost, should not use ‘ip ospf cost …’ on interface. Make cost on ethernet as 90. auto-cost-reference-bandwidth 900

12. Rip (2)
Rip on R1 e0/0, mutual redistribution with ospf. Should receive only 199.172.x.0, make and as one network on your ospf topology, also advertise Only class B 135.x.0.0/16 can be advertised from ospf to rip. There are 4 networks received by rip:,,, router rip redistribute ospf 3 metric 2 network router ospf 3 redistribute rip subnet summary-address distribute-list 1 out rip access-list 1 permit

13. SAP (2)
vlana’s sap is interferenced by something, assume that there is no servers on vlana, make the sap advertise only when it changed. At R2, R3, R6, set on interface: ipx sap-incremental eigrp 3

14. ISDN (4)
Only R5 can generate the call, use chap authentication, but R5 should not challenge R3, R5 should not use its own name to authenticate, must use userx. Oneway authentication. Oneway dialer map At R5: user user3 password cisco user R3 password cisco ini bri0 dialer map ip broadcast 68020301 ppp chap hostname user3

At R3: user user3 password cisco user R3 password cicso int bri0 ppp authentication chap

15. ISDN routing (2)
Setup R3 and R5 such that when R5 can access the topology when its serial interface is down. At R5 router ospf 3 network area 5 network area 5 area 1 virtual-link area 1 virtual-link int bri0 ip ospf demand-circuit I use backup interface also, but the protor said its wrong (if interface is up, but the dlci mapping in telecom is wrong, the isdn will not up). So just demand-circuit is ok. Make the loopback interface at area 5, and setup two virtual-link to make sure the area5 and the loopback interface is seen by the topology when serial is down and isdn is up.

16 ATM (2)
R6, no subinterface, no autolearn ip address from client. vpi: 0, vci: 10x. ip address: 192.1.x.1, remote ATM router ip: 192.1.x.254 int atm 3/0 pvc 0/103 protocol ip broadcast no inarp

17. VPN (2)
You have a VPN client, they use CIDR, some of your client’s employees are connected at R5’s ethernet, their gateway is You can use any network in to build the VPN. VPN still on function when R5’s serial is down. Setup tunnel between R5 and R6’s secondary ip address at R5’s e0: R6: int tunnel 0 ip address tunnel source loopback 0 tunnel destination
