[Offer] Skill Semester 4 Question and answer

[4cisco]

Note: Student should read the following questions carefully and ask the instructor anything you feel unclear.
The answers should be written down below detailedly (including all relevant theory and commands)

1 – Write at least 2 commands to find out DLCIs of connections attached to a frame-relay router ?

2 – If you configure frame-relay network (with Cisco router as Frame-relay switch) and there is an Intel router in the network, what are the points must you notice in your configuration? What are the
commands to change?

3 – Write the necessary interface configuration for ppp multilink over interface S0/0 and S0/1 ?

4 – What are the first and the second method that router get its DLCIs? When do you use the first method and when do you use the second method?

5 – Explain the functions of the following command, how the process will occur:
ppp authentication chap pap

6 – Configure router NAT/PAT with global address 9.1.1.1-9.1.1.15 and the inside address 10.0.0.0/8?

7 – How do you see information about incoming and outgoing call, how do you see information about the three layers of BRI interface regarding ISDN parameters?

Answer

1 – Write at least 2 commands to find out DLCIs of connections attached to a frame-relay router?
-show frame-relay map
- show frame-relay pvc

2 – If you configure frame-relay network (with Cisco router as Frame-relay switch) and there is an
Intel router in the network, what are the points must you notice in your configuration? What are the
commands to change?
-by default Cisco router using frame-relay format cisco.

-using command:encapsulation frame-relay eitf

3 – Write the necessary interface configuration for ppp multilink over interface S0/0 and S0/1 Interface Multilink 1?

Ip address 1.1.1.2 255.255.0.0
Ppp multilink

Interface s0/0
No ip address
Encapsulation ppp
Clock rate 64000
Ppp multilink
Ppp multilink group 1

Interface s0/1
No ip address
Encapsulation ppp
ppp multilink
Ppp multilink group 1

4 – What are the first and the second method that router get its DLCIs? When do you use the first method and when do you use the second method?
-using static map: when remote router does not support inverse arp, configuring OSPF over Frame-
relay, or want to control broadcast traffic while using routing
- dinamic map using inverse ARP

5 – Explain the functions of the following command, how the process will occur:
ppp authentication chap pap
- configure the interface ppp authentication. First method (chap) is using first. If suggest using
method 2 (or method 1 is refuse) -> using method 2(pap)

6 – Configure router NAT/PAT with global address 9.1.1.1-9.1.1.15 and the inside address 10.0.0.0/8
-(config)# ip nat pool pool_name 9.1.1.1 9.1.1.15 netmask 255.0.0.0
-(config)#access-list 1 permit 10.0.0.0 0.255.255.255
-(config)#ip nat inside source list 1 pool pool_name overload
-(config)#interface e0/0
-(config-if)#ip nat inside
-(config)#interface s0/0
-(config-if)#ip nat outside

7 – How do you see information about incoming and outgoing call, how do you see information about the three layers of BRI interface regarding ISDN parameters?
-show dialer

-show interface BRI0
