I. Mô hình và yêu cầu
1. Mô hình

​
2. Yêu cầu
- Cấu hình NAT để các Router bên trong ra internet
- Cấu hình Redistribute sao cho Router và PC bên trong ra được internet
- Sơ đồ IP:

[TABLE="class: grid, width: 800"]

[/TABLE]

​
II. Triển khai
1. Trên R1
- Cấu hình IP, NAT overload và lan truyền default-route vào bên trong

[TABLE="class: outer_border, width: 500"]
[TR]
[TD]R4(config)#int f0/0
R4(config-if)#ip address dhcp
R4(config-if)#no shut
R4(config-if)#int f0/1
R4(config-if)#ip address 10.4.4.4 255.255.255.0
R4(config-if)#no shutdown

R4(config)#access-list 1 permit any
R4(config)#ip nat inside source list 1 interface f0/0 overload

R4(config)#int f0/0
R4(config-if)#ip nat outside
R4(config-if)#int f0/1
R4(config-if)#ip nat inside

R4(config)#router ospf 1
R4(config-router)#network 10.4.4.4 0.0.0.0 area 0
R4(config-router)#default-information originate[/TD]
[/TR]
[/TABLE]

​
2. Trên R3
- Cấu hình IP, Routing(OSPF và RIP), lan truyền default-route và redistribute để phân phối các lớp mạng trong vùng OSPF và RIP với nhau.

[TABLE="class: outer_border, width: 500"]
[TR]
[TD]R3(config)#int f0/0
R3(config-if)#ip address 10.4.4.3 255.255.255.0
R3(config-if)#no shutdown
R3(config-if)#int f0/1
R3(config-if)#ip address 10.3.3.3 255.255.255.0
R3(config-if)#no shutdown

R3(config)#router ospf 1
R3(config-router)#network 10.4.4.3 0.0.0.0 area 0
R3(config-router)#redistribute rip subnets

R3(config)#router rip
R3(config-router)#network 10.3.3.3
R3(config-router)#default-information originate
R3(config-router)#redistribute ospf 1 metric 5[/TD]
[/TR]
[/TABLE]

​
3. Trên R2
- Cấu hình IP, Routing( RIP và EIGRP), lan truyền default-route và redistribute để phần phối các lớp mạng trong vùng định tuyến EIGRP và RIP với nhau.

[TABLE="class: outer_border, width: 500"]
[TR]
[TD]R2(config-if)#int f0/0
R2(config-if)#ip address 10.3.3.2 255.255.255.0
R2(config-if)#no shutdown
R2(config-if)#int f0/1
R2(config-if)#ip address 10.2.2.2 255.255.255.0
R2(config-if)#no shutdown

R2(config)#router rip
R2(config-router)#network 10.3.3.2
R2(config-router)#redistribute eigrp 1 metric 5

R2(config)#router eigrp 1
R2(config-router)#network 10.2.2.2 0.0.0.0
R2(config-router)#redistribute static
R2(config-router)#redistribute rip metric 100000 100 255 1 1500[/TD]
[/TR]
[/TABLE]

​
4. Trên R1
- Cấu hình IP, Routing: EIGRP và static route và thực hiện redistribute static.

[TABLE="class: outer_border, width: 500"]
[TR]
[TD]R1(config)#int f0/0
R1(config-if)#ip address 10.2.2.1 255.255.255.0
R1(config-if)#no shutdown
R1(config-if)#int f0/1
R1(config-if)#ip address 10.1.1.1 255.255.255.0
R1(config-if)#no shutdown

R1(config)#router eigrp 1
R1(config-router)#network 10.2.2.1 0.0.0.0
R1(config-router)#redistribute static metric 100000 100 255 1 1500

R1(config)#ip route 192.168.1.0 255.255.255.0 10.1.1.5[/TD]
[/TR]
[/TABLE]

​
5. Trên R5
- Cấu hình IP và trỏ default-route về R1

[TABLE="class: outer_border, width: 500"]
[TR]
[TD]R5(config)#int f0/0
R5(config-if)#ip address 10.1.1.5 255.255.255.0
R5(config-if)#no shutdown
R5(config-if)#int f0/1
R5(config-if)#ip address 192.168.1.254 255.255.255.0
R5(config-if)#no shutdown
R5(config)#int loopback 0
R5(config-if)#ip address 1.1.1.1 255.255.255.0

R5(config)#ip route 0.0.0.0 0.0.0.0 10.1.1.1[/TD]
[/TR]
[/TABLE]

​
III. Kết quả
- PC ping ra internet thành công
