Second, the operation of the problem (a total of 80)

Please configure the following topology experiment, save the topology, set up a text document, follow the switch-Router 1 2 3 4 in order to copy and paste the show running-config of each device, save the text document and the topology, submit the compressed package naming format is: X group-Name.

Using the Cisco Packet Tracer Software, (1) R1 connect the company intranet, through the R1 access to the external network, and the external network has a server R5, now through the configuration can make the company's PC Access server R5.

Requirements:

1. Configure the IP address according to the topology map.

PC0:192.168.10.2/24 Gateway: 192.168.10.254/24

PC1:192.168.20.2/24 Gateway: 192.168.20.254/24

The router interface address is shown in the topology diagram, such as r1-f0/0:172.16.12.1/24

The router configures the loopback address loopback 1, 10.x.x.x/24 for example: r1:10.1.1.1/24

PC0:

PC1:

Building configuration ...

[OK]

Router (config) #hostname R2//change name

R1#erase Startup-config//Clear All

R1#reload//restart

Continue with Configuration dialog? [Yes/no]: No

1. PC 0 divides the VLAN 10,pc1 into VLAN20, choosing the right method to make PC0 and PC1 interoperable

Partitioning the PC into VLANs (operation on the switch)

Switch (config) #vlan 10//Create VLAN 10

Switch (Config-vlan) #ex//exit VLAN 10 mode

Switch (config) #vlan 20//Create VLAN 20

Switch (Config-vlan) #ex

Switch (config) #int f0/1//Enter F0/1 port

Switch (config-if) #switchport MO Access//enable Access Protocol

Switch (config-if) #switchport access VLAN 10//Divide the PC under the F0/1 port into VLAN 10

Switch (config-if) #int F0/3//Enter F0/3 port

Switch (config-if) #switchport MO Access/enable Access Protocol

Switch (config-if) #switchport AC VLAN 20//Divide the PC under the F0/3 port into VLAN 20

Switch#show Run//View all Configurations

Change switch to trunk mode (operation on switch)

Switch (config) #int F0/2//Enter out interface

Switch (config-if) #switchport mode trunk//Turn out interface to trunk mode

Switch (CONFIG-IF) #no shutdown//Open port

Single-arm routing (operation from the nearest router on the switch)

Router (config-subif) #int F 1/0

Router (CONFIG-SUBIF) #no shutdown (default is off on route)

Router (config) #int fastethernet 1/0.1 (enter sub-interface)

Router (config-subif) #encapsulation dot1q 10 (Encapsulated dot1q protocol, same as the VLAN that the PC belongs to)

Router (config-subif) #ip add 192.168.10.254 255.255.255.0

Router (config-subif) #int F 1/0.2

Router (config-subif) #encapsulation dot1q 20 (Encapsulated dot1q protocol, same as VLAN with IP address configured below)

Router (config-subif) #ip add 192.168.20.254 255.255.255.0

Gray Section , the address is the same as the default gateway of PC, please do not match the wrong

Ping between PC0 and PC1

3, R1 all interface (including loopback 1), R2 f0/0 do rip, version number 2

R1 (config) #router rip//Enter RIP protocol

R1 (Config-router) #version 2//Select version number (typically 1 version)

R1 (config-router) #no auto-summary//Turn off Auto Summary

R1 (config-router) #network 10.1.1.0//Declaration Lo1

R1 (config-router) #network 192.168.10.0//Declaration f1/0.1

R1 (config-router) #network 192.168.20.0//Declaration f1/0.2

R1 (config-router) #network 172.16.12.0//Declaration f0/0

R2 (config) #router rip

R2 (config-router) #version 2

R2 (config-router) #no au

R2 (config-router) #network 172.16.12.0

4. To do OSPF, the f1/0 and Loopback1 interfaces of R2 and R3 belong to the 0,R3, R4 of OSPF area f0/0 and R4

F1/0 and Loopback1 belong to OSPF area 1 and are divided into corresponding regions according to the topology, and the route ID corresponds to loopback 1

R2 (config) #router OSPF 100//Enter the OSPF protocol (110 or less, as long as it is the same number on the line)

R2 (config-router) #router-id 10.2.2.2//Assign IP to the route, similar to the identity card

R2 (config-router) #network 10.2.2.0 0.0.0.255 Area 0//Declare LO1, partition

R2 (config-router) #network 172.16.23.0 0.0.0.255 Area 0//Declare f1/0, partition

R2#show Run//View all Configurations

R3

R4

5. Pick the right device, do RIP and OSPF redistribution, and learn the routing entries to each other

Choose to redistribute on R2 because it has two protocols at the same time

R2 (config) #router OSPF 100//Enter the OSPF protocol

R2 (config-router) #redistribute RIP subnets//Assign RIP

R2 (Config-router) #ex//return to upper level

R2 (config) #router rip

R2 (config-router) #redistribute OSPF metric 1//Assign OSPF protocol

6. Use NAT Pat mode address translation on egress router R4, based on interface

R4 (config) #ip nat inside source List 1 interface f1/0 overload//extranet interface

R4 (config) #access-list 1 Permit 192.168.10.0 0.0.0.255//pc0

R4 (config) #access-list 1 Permit 192.168.20.0 0.0.0.255//PC1

R4 (config) #int f0/0//Enter into interface

R4 (config-if) #ip NAT inside//Announce Intranet

R4 (config-if) #int f1/0//Enter out interface

R4 (config-if) #ip NAT outside//announce extranet

7. The final implementation of PC0 and PC1 can be accessed R5

Need:

Show ip route on R1

Show ip NAT translations on R4
