EIGRP Multi-AF (Different Named EIGRP and Autonomous System)
Oke guys, kemarin kita telah membahas tentang EIGRP Multi-AF atau EIGRP yang menggunakan penamaan dengan huruf. Sekarang kita masih di pembahasan itu tapi perbedaannya kemarin kita membuat Multi-AF tapi masih satu AS, sekarang kita akan mencoba membuat bebeapa instance yang isinya beberapa AS. Let's check it out.
Topologi:
Skenario:
Kita akan mengkonfigurasikan EIGRP pada area biru dengan AS 10, dan area orange dengan AS 20.
Pertama kita beri IP terlebih dahulu pada setiap devices
Konfigurasi di R1:
R1(config)#int fa0/0Konfigurasi di R2:
R1(config-if)#no sh
R1(config-if)#ip add 14.14.14.1 255.255.255.0

R3(config-if)#ip add 33.33.33.33 255.255.255.255
Konfigurasi di R4:
R4(config)#int fa0/0

R4(config-if)#int lo1
R4(config-if)#ip add 44.44.44.44 255.255.255.255
Konfigurasi di R5:
R5(config)#int fa0/0
R5(config-if)#no sh
R5(config-if)#ip add 35.35.35.5 255.255.255.0
R5(config-if)#int lo0
R5(config-if)#ip add 5.5.5.5 255.255.255.255
R5(config-if)#int lo1
R5(config-if)#ip add 55.55.55.55 255.255.255.255
Setelah kita konfigurasikan IP di semua router, sekarang kita konfigurasikan EIGRP named sesuai yang ada di topologi
Konfigurasi di R1:
R1(config)#router eigrp IDNKonfigurasi di R2:
R1(config-router)#address-family ipv4 autonomous-system 10
R1(config-router-af)#eigrp router-id 1.1.1.1
R1(config-router-af)#net 12.12.12.1 0.0.0.0
R1(config-router-af)#net 14.14.14.1 0.0.0.0
R1(config-router-af)#net 1.1.1.1 0.0.0.0
R1(config-router-af)#net 11.11.11.11 0.0.0.0
R2(config)#router eigrp IDNKonfigurasi di R3:
R2(config-router)#address-family ipv4 autonomous-system 10
R2(config-router-af)#eigrp router-id 2.2.2.2
R2(config-router-af)#net 12.12.12.2 0.0.0.0
R2(config-router-af)#net 2.2.2.2 0.0.0.0
R2(config-router-af)#net 22.22.22.22 0.0.0.0
R2(config-router-af)#router eigrp cisco
R2(config-router)#add ipv4 au 20
R2(config-router-af)#eigrp router-id 2.2.2.2
R2(config-router-af)#net 23.23.23.2 0.0.0.0
R3(config)#router eigrp cisco
R3(config-router)#add ipv4 au 20
R3(config-router-af)#eigrp router-id 3.3.3.3
R3(config-router-af)#net 23.23.23.3 0.0.0.0
R3(config-router-af)#net 35.35.35.3 0.0.0.0
R3(config-router-af)#net 3.3.3.3 0.0.0.0
R3(config-router-af)#net 33.33.33.33 0.0.0.0
Konfigurasi di R4:
R4(config)#router eigrp IDN
R4(config-router)#add ipv4 au 10
R4(config-router-af)#eigrp router-id 4.4.4.4
R4(config-router-af)#net 14.14.14.4 0.0.0.0
R4(config-router-af)#net 4.4.4.4 0.0.0.0
R4(config-router-af)#net 44.44.44.44 0.0.0.0
Konfigurasi di R5:
R5(config)#router eigrp cisco
R5(config-router)#add ipv4 au 20
R5(config-router-af)#net 35.35.35.5 0.0.0.0
R5(config-router-af)#net 5.5.5.5 0.0.0.0
R5(config-router-af)#net 55.55.55.55 0.0.0.0
Setelah kita konfigurasikan EIGRP namednya, sekarang kita cek routing table R4, apakah dia sudah mendapatkan informasi tentang network di R3 dan R5.

Disini terlihat bahwa network pada R3 dan R5 belum terdaftar di routing table R4, berarti kita harus melakukan redistribute agar AS 10 pada jaringan R1, R2, dan R4 bisa terhubung dengan AS 20 pada R2, R3, R5. Kita lakukan redistribute di R2.
Konfigurasi di R2:
R2(config)#router eigrp IDN
R2(config-router)#address-family ipv4 au 10
R2(config-router-af)#topology base
R2(config-router-af-topology)#redistribute eigrp 20
R2(config-router-af-topology)#router eigrp cisco
R2(config-router)#add ipv4 au 20
R2(config-router-af)#topology base
R2(config-router-af-topology)#redistribute eigrp 10
Setelah kita lakukan redistribute di R2, seharusnya network di R3 dan R5 sudah terlihat di routing table R4.

Nah disini terlihat bahwa network pada R3 dan R5 sudah terdaftar di routing table di R4. Berarti secara otomatis R4 sudah dapat terhubung ke R3 dan R5 begitupun sebaliknya. Untuk verifikasi coba lakukan tes ping dari R4 ke IP loopback R5.
R4#ping 55.55.55.55
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 55.55.55.55, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 52/241/492 ms
Disini kita telah berhasil melakukan ping.
Jadi kesimpulannya pada EIGRP Multi-AF ini, untuk named tidak mempengaruhi proses adjacency suatu jaringan EIGRP, tapi yang mempengaruhi tetap AS, walaupun antar router berbeda named itu tidak berpengaruh. Dan juga tiap named itu hanya bisa memuat satu AS saja.
Oke dengan ini lab kali ini dinyatakan BERHASIL!!!!
Selesaaiii.......
Mungkin sampai sini dulu.... dan stay and this blog....
And Wassalamualaikum......
Jangan pernah bosan untuk belajar, selalu belajar dan temukan hal baru. Karena belum tentu hasil yang akan kita dapat itu dapat diraih dengan usaha yang mudah, semudah menjatuhkan sesuatu. Bisa saja kita harus mendapatkan dengan usaha yang sulit, seperti menjadi sebuah benda kecil ditumpukkan jerami.
