Lab 5 EIGRP - Redistribute OSPF

Assalamu'alaikum Warohmatullahi Wabarokatuh...
baik sahabat configer kali ini saya akan sedikit sharing mengenai EIGRP Redistribusi Static redistribusi adalah proses dimana router meneruskan paket data dalam sebuah jaringan dengan ip address yang berbeda yang bertujuan supaya kita dapat menggunakan routing static ataupun dynamic 

kali ini kita akan coba Redistribusi RIP EIGRP untuk skema jaringannya seperti ini 

Sekarang kita akan konfigurasi ip dan eigrp pada semua router :

Router 1

R1(config)#int lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.255
R1(config)#int se1/0
R1(config-if)#ip add 12.12.12.1 255.255.255.0
R1(config-if)#no shutdown
R1(config)#router eigrp 10
R1(config-router)#net 1.1.1.1 0.0.0.0
R1(config-router)#net 12.12.12.1 0.0.0.0
R1(config-router)#no auto-summary

Router 2

R2(config)#int lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.255
R2(config-if)#exit
R2(config)#int se1/0
R2(config-if)#ip add 12.12.12.2 255.255.255.0
R2(config-if)#no sh
R2(config)#int f0/0
R2(config-if)#ip add 23.23.23.2 255.255.255.0
R2(config-if)#no sh
R2(config)#router eigrp 10
R2(config-router)#net 12.12.12.2 0.0.0.0
R2(config-router)#net 2.2.2.2 0.0.0.0
R2(config-router)#net 23.23.23.2 0.0.0.0
R2(config-router)#no auto-summary

Router3

R3(config)#int lo0
R3(config-if)#ip add 3.3.3.3 255.255.255.255
R3(config-if)#ex
R3(config)#int f0/0
R3(config-if)#ip add 23.23.23.1 255.255.255.0
R3(config-if)#no sh
R3(config-if)#ex
R3(config)#router eigrp 10
R3(config-router)#net 3.3.3.3 0.0.0.0
R3(config-router)#net 23.23.23.1 0.0.0.0
R3(config-router)#no auto-summary

setelah selesai kita cek ip route dan test ping koneksinya

R1#sh ip route
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2
i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
ia - IS-IS inter area, * - candidate default, U - per-user static route
o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
+ - replicated route, % - next hop override
Gateway of last resort is not set
1.0.0.0/32 is subnetted, 1 subnets
1.1.1.1 is directly connected, Loopback0
2.0.0.0/32 is subnetted, 1 subnets
2.2.2.2 [90/2297856] via 12.12.12.2, 00:10:43, Serial1/0
3.0.0.0/32 is subnetted, 1 subnets
3.3.3.3 [90/2300416] via 12.12.12.2, 00:05:37, Serial1/0
12.0.0.0/8 is variably subnetted, 2 subnets, 2 masks
12.12.12.0/24 is directly connected, Serial1/0
12.12.12.1/32 is directly connected, Serial1/0
23.0.0.0/24 is subnetted, 1 subnets
23.23.23.0 [90/2172416] via 12.12.12.2, 00:05:39, Serial1/0

R1#ping 1.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/2/4 ms

R1#ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 8/11/16 ms

R1#ping 3.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/32/40 ms

setelah kita selesai mengkonfigurasi EIGRP sekarang kita akan membuat interface loopback di R1

R1(config)#int lo20
R1(config-if)#ip add 20.20.20.1 255.255.255.255

selanjutnya kita tambahkan kedalam OSPF

R1(config)#router ospf 1
R1(config-router)net 20.20.20.1 0.0.0.0 area 0

lakukan redistribusi EIGRP di R1

R1(config)#router eigrp 10
R1(config)#redistribute ospf 1 metric 1 1 1 1 1

Note : untuk meredistribusi satu routing protokol ke protokol lainnya nilai metric harus di sesuaikan

sekarang kita cek routing tablenya di router 3

R3#sh ip route eigrp 
Codes: L - local, C - connected, S - static, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area 
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
       E1 - OSPF external type 1, E2 - OSPF external type 2
       i - IS-IS, su - IS-IS summary, L1 - IS-IS level-1, L2 - IS-IS level-2
       ia - IS-IS inter area, * - candidate default, U - per-user static route
       o - ODR, P - periodic downloaded static route, H - NHRP, l - LISP
       + - replicated route, % - next hop override

Gateway of last resort is not set

      1.0.0.0/32 is subnetted, 1 subnets
D        1.1.1.1 [90/2300416] via 23.23.23.2, 00:36:09, FastEthernet0/0
      2.0.0.0/32 is subnetted, 1 subnets
D        2.2.2.2 [90/156160] via 23.23.23.2, 00:36:09, FastEthernet0/0
      12.0.0.0/24 is subnetted, 1 subnets
D        12.12.12.0 [90/2172416] via 23.23.23.2, 00:36:09, FastEthernet0/0
      20.0.0.0/32 is subnetted, 1 subnets
D EX     20.20.20.1 [170/2172416] via 23.23.23.2, 00:36:09, FastEthernet0/0

terlihat ada ip 20.20.20.1 dengan Label D EX = EIGRP External artinya ip tersebut berasal dari luar EIGRP karena tadi kita melakukan routing OSPF yang di redistribusi ke EIGRP,hingga R3 dapat mengenali ip address tersebut dan ping nya pun sudah berhasil

R3#ping 20.20.20.1 
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 20.20.20.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/25/40 ms
