Các bươc thực hiên

1. Đăt hostname, cấu hình cho các cổng trên router R1

2. Đăt hostname, cấu hình cho cổng trên router R2

R3(config-if)# int Ethernet0R3(config-if)# ip address 9.1.3.1 255.255.255.0R3(config-if)# no keepaliveR3(config-if)# no shut


4. Cấu hình giao thưc đinh tuyến IGRP vơi AS là 10 trên router R3

R3(config)# router igrp 10 ← kich hoat qua trinh đinh tuyên IGRP trên router vơi AS la 10

R3(config-router)# network 9.0.0.0 ← chi ra mang nao se chay IGRPR3(config-router)# endR3#

+ Lưu y răng vì IGRP và RIP thuôc dang classfull nên se tự đông thực hiên summarization vê đia chi classfull lơp A.

5. Cấu hình giao thưc đinh tuyến RIP trên router R2

R2(config)# router ripR2(config-router)# network 9.0.0.0R2(config-router)# network 10.0.0.0R2(config-rputer)# endR2#

6. Cấu hình giao thưc đinh tuyến RIP và IGRP cho mang 9.0.0.0 trên router R1

7. Trên router R1, ta cần đảm bảo răng RIP updates không gưi sang R3 (chay IGRP) và đảm bảo IGRP updates tư R3 không gưi sang R2(chay RIP). Do đo ta cần thực hiên passive interface trên router R1 để đảm bảo không quảng cáo các thông tin update ra mang ngoài.

8. Kiểm tra bảng đinh tuyến

–Dung lênh clear ip route * để xoá toàn bô route tư bảng đinh tuyến.

R1# clear ip route *

–Xem bảng đinh tuyến trên R1 băng lênh show ip route.

R1# show ip route...Gateway of last resort is not set9.0.0.0/24 is subnetted, 3 subnetsC 9.1.1.0 is directly connected, Serial0C 9.1.2.0 is directly connected, Serial1I 9.1.3.0 [100/80225] via 9.1.2.2, 00:00:31, Serial1R 10.0.0.0/8 [120/1] via 9.1.1.2, 00:00:15, Serial0R1#

–Xem bảng đinh tuyến trên R2 băng lênh show ip route.

R2# show ip route...9.0.0.0/24 is subnetted, 2 subnetsC 9.1.1.0 is directly connected, Serial0R 9.1.2.0 [120/1] via 9.1.1.1, 00:00:27, Serial010.0.0.0/24 is subnetted, 1 subnetsC 10.1.1.0 is directly connected, Ethernet0R2#

Xem bảng đinh tuyến trên R2 ta thấy R2 không kết nối đươc vơi mang 9.1.3.0/24. Do đo, ta cần cấu hình redistribute trên router R1 để cho phep R2 thấy mang 9.1.3.0/24.

Redistribution đinh nghia cách thưc trao đổi routing updates giữa các giao thưc đinh tuyến khác nhau. Môi giao thưc đinh tuyến co cách đinh nghia vê metric khác nhau, do đo khi thực hiên redistribution ta cần phải chuyển đổi dang metric sao cho phu hơp vơi giao thưc đinh tuyến đo.

9. Để R2 thấy đươc R3 ta thực hiên redistribute IGRP trong RIP vơi hop count là 1

R1(config)# router ripR1(config-router)# redistribute igrp 10 metric 1

10. Để R3 thấy đươc R2 ta thực hiên redistribute RIP trong IGRP, sư dung ky tự giup đơ ? để hiển thi IGRP metric.

R1(config)# router igrp 10R1(config-router)# redistribute rip ?Metric Metric for redistributed routedroute-map Route map referenceR1(config-router)# redistribute rip metric ?<1-4294967295> Bandwidth metric in Kbits per secondR1(config-router)# redistribute rip metric 128 ?<0-4294967295> IGRP delay metric, in 10 microsecond unitsR1(config-router)# redistribute rip metric 128 20000 ?<0-255> IGRP reliability metric where 255 is 100% reliableR1(config-router)# redistribute rip metric 128 20000 255 ?<0-255> IGRP effective bandwidth metric (Loading) where 255 is 100% loadedR1(config-router)# redistribute rip metric 128 20000 255 1 ? <0-4294967295> IGRP MTU of the pathR1(config-router)# redistribute rip metric 128 20000 255 1 1500

11. Sau khi cấu hình, thực hiên clear ip route * và xem lai bảng đinh tuyến trên router R2. Ping mang 9.1.3.0 để kiểm tra đa kết nối đươc vơi mang IGRP chưa.

R2# show ip route9.0.0.0/24 is subnetted, 3 subnetsC 9.1.1.0 is directly connected, Serial0R 9.1.2.0 [120/1] via 9.1.1.1, 00:00:09, Serial0R 9.1.3.0 [120/1] via 9.1.1.1, 00:00:09, Serial010.0.0.0/24 is subnetted, 1 subnetsC 10.1.1.0 is directly connected, Ethernet0R2#

12. Xem bảng đinh tuyến trên router R3. Ping mang 10.1.1.0 để kiểm tra đa kết nối vơi mang RIP chưa.

R3# show ip route

9.0.0.0/24 is subnetted, 3 subnetsI 9.1.1.0 [100/84000] via 9.1.2.1, 00:00:58, Serial0C 9.1.2.0 is directly connected, Serial0C 9.1.3.0 is directly connected, Ethernet0I 10.0.0.0/8 [100/102000] via 9.1.2.1, 00:00:58, Serial0R3#R3#ping 10.1.1.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 9.1.3.1, timeout is 2 seconds:! ! ! ! !Success rate is 100 percent (5/5), round-trip min/avg/max = 28/29/32 ms

13. Mơ rông vấn đê hơn, ta thêm môt subnet mơi vào R3 băng cách cấu hình interface loopback 10.1.2.1/24 sư dung IGRP.

R3(config)# int loopback0R3(config-if)# ip address 10.1.2.1 255.255.255.0R3(config-if)# router igrp 10R3(config-router)# network 10.0.0.0

Ban đầu, R3 se không quảng cáo mang 10.0.0.0 đến router R1 vì R1 chi biết đến mang 10.0.0.0/8 thông qua quảng cáo RIP vơi AD là 120 tư R2.

R1# show ip routeGateway of last resort is not set9.0.0.0/24 is subnetted, 3 subnetsC 9.1.1.0 is directly connected, Serial0C 9.1.2.0 is directly connected, Serial1I 9.1.3.0 [100/80225] via 9.1.2.2, 00:00:31, Serial1R 10.0.0.0/8 [120/1] via 9.1.1.2, 00:00:15, Serial0R1#

Khi IGRP update tư R3 gưi đến R1, bảng đinh tuyến trên R1 se thay đổi như sau:

R1# show ip routeGateway of last resort is not set9.0.0.0/24 is subnetted, 3 subnetsC 9.1.1.0 is directly connected, Serial0C 9.1.2.0 is directly connected, Serial1

I 9.1.3.0 [100/80225] via 9.1.2.2,00:00:53, Serial1I 10.0.0.0/8 [100/80225] via 9.1.1.2, 00:00:53, Serial1R1#

Nguyên do cua sự thay đổi này là do R3 sư dung IGRP nên co AD=100 thấp hơn RIP (AD=120) nên R1 se gưi tất cả các lưu lương cho mang 10.0.0.0 qua router R3.

R1#ping 10.1.1.1Type escape sequence to abort.Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:. . . . .Success rate is 0 percent (0/5)

14. Để giải quyết vấn đê này ta cấu hình static route đến R2:

R1(config)# ip route 10.1.1.0 255.255.255.0 Serial0

15. Kiểm tra kết quả thực hiên
