Sebelumnya, kita telah membahas overview dari superlab ini. Selanjutnya pada artikel ini kita akan membahas konfigurasi routing protocol IGP pada jaringan ISP, dalam hal ini routing protocol IGP yang akan kita gunakan adalah OSPF.
Berikut topologi jaringan ISP yang akan kita konfigurasikan OSPF

| Gambar 1 Topologi jaringan ISP |
Pertama, kita konfigurasikan IP Address pada router-router yang berada pada jaringan ISP tersebut. Nantinya kita perlu menambahkan interface bridge pada setiap router untuk keperluan pembuatan IP Address Loopback.
Oke langsung saja, berikut konfigurasi IP Address pada seluruh router
[admin@R1] > int bri ad name l0[admin@R1] > ip ad [admin@R1] /ip address> ad ad 12.12.12.1/24 int ether1 [admin@R1] /ip address> ad ad 1.1.1.1/32 int l0
[admin@R2] > int br ad na l0 [admin@R2] > ip ad [admin@R2] /ip address> ad ad 12.12.12.2/24 int ether1 [admin@R2] /ip address> ad ad 23.23.23.2/24 int ether2 [admin@R2] /ip address> ad ad 24.24.24.2/24 int ether3 [admin@R2] /ip address> ad ad 2.2.2.2/32 int l0
[admin@R3] > int br ad na l0 [admin@R3] > ip ad [admin@R3] /ip address> ad ad 23.23.23.3/24 int ether1 [admin@R3] /ip address> ad ad 34.34.34.3/24 int ether2 [admin@R3] /ip address> ad ad 35.35.35.3/24 int ether3 [admin@R3] /ip address> ad ad 36.36.36.3/24 int ether4 [admin@R3] /ip address> ad ad 3.3.3.3/32 int l0
[admin@R4] > int br ad na l0 [admin@R4] > ip ad [admin@R4] /ip address> ad ad 24.24.24.4/24 int ether1 [admin@R4] /ip address> ad ad 34.34.34.4/24 int ether2 [admin@R4] /ip address> ad ad 47.47.47.4/24 int ether3 [admin@R4] /ip address> ad ad 46.46.46.4/24 int ether4 [admin@R4] /ip address> ad ad 4.4.4.4/32 int l0
[admin@R5] > int br ad n l0 [admin@R5] > ip ad [admin@R5] /ip address> ad ad 35.35.35.5/24 int ether1 [admin@R5] /ip address> ad ad 5.5.5.5/32 int l0
[admin@R6] > int br ad na l0 [admin@R6] > ip ad [admin@R6] /ip address> ad ad 36.36.36.6/24 int ether1 [admin@R6] /ip address> ad ad 46.46.46.6/24 int ether2 [admin@R6] /ip address> ad ad 6.6.6.6/32 int l0
[admin@R7] > int br ad na l0 [admin@R7] > ip ad [admin@R7] /ip address> ad ad 47.47.47.7/24 int ether1 [admin@R7] /ip address> ad ad 7.7.7.7/32 int l0
Oke konfigurasi IP Address pada seluruh router ISP sudah selesai. selanjutnya kita konfigurasikan routing protocol OSPF pada seluruh router
[admin@R1] /ip address> /rout ospf net[admin@R1] /routing ospf network> ad net 12.12.12.0/24 ar b [admin@R1] /routing ospf network> ad net 1.1.1.1/32 are b
[admin@R2] /ip address> /ro ospf [admin@R2] /routing ospf> net ad net 12.12.12.0/24 are b [admin@R2] /routing ospf> net ad net 23.23.23.0/24 are b [admin@R2] /routing ospf> net ad net 24.24.24.0/24 are b [admin@R2] /routing ospf> net ad net 2.2.2.2/32 are b
[admin@R3] /ip address> /ro ospf net [admin@R3] /routing ospf network> ad net 23.23.23.0/24 are b [admin@R3] /routing ospf network> ad net 34.34.34.0/24 are b [admin@R3] /routing ospf network> ad net 35.35.35.0/24 are b [admin@R3] /routing ospf network> ad net 36.36.36.0/24 are b [admin@R3] /routing ospf network> ad net 3.3.3.3/32 are b
[admin@R4] /ip address> /ro ospf net [admin@R4] /routing ospf network> ad net 24.24.24.0/24 are b [admin@R4] /routing ospf network> ad net 34.34.34.0/24 are b [admin@R4] /routing ospf network> ad net 46.46.46.0/24 are b [admin@R4] /routing ospf network> ad net 47.47.47.0/24 are b [admin@R4] /routing ospf network> ad net 4.4.4.4/32 are b
[admin@R5] /ip address> /ro ospf [admin@R5] /routing ospf> net ad net 35.35.35.0/24 are b [admin@R5] /routing ospf> net ad net 5.5.5.5/32 are b
[admin@R6] /ip address> /ro ospf net [admin@R6] /routing ospf network> ad net 36.36.36.0/24 are b [admin@R6] /routing ospf network> ad net 46.46.46.0/24 are b [admin@R6] /routing ospf network> ad net 6.6.6.6/32 are b
[admin@R7] /ip address> /ro ospf net [admin@R7] /routing ospf network> ad net 47.47.47.0/24 are b [admin@R7] /routing ospf network> ad net 7.7.7.7/32 are b
Oke konfigurasi OSPF sudah selesai, lanjut kita lakukan pengecekan routing tabel pada seluruh router, pastikan seluruh router mengenali IP loopback dari seluruh router lain
[admin@R1] /routing ospf network> /ip ro prFlags: X - disabled, A - active, D - dynamic, C - connect, S - static, r - rip, b - bgp, o - ospf, m - mme, B - blackhole, U - unreachable, P - prohibit # DST-ADDRESS PREF-SRC GATEWAY DISTANCE 0 ADC 1.1.1.1/32 1.1.1.1 l0 0 1 ADo 2.2.2.2/32 12.12.12.2 110 2 ADo 3.3.3.3/32 12.12.12.2 110 3 ADo 4.4.4.4/32 12.12.12.2 110 4 ADo 5.5.5.5/32 12.12.12.2 110 5 ADo 6.6.6.6/32 12.12.12.2 110 6 ADo 7.7.7.7/32 12.12.12.2 110 7 ADC 12.12.12.0/24 12.12.12.1 ether1 0 8 ADo 23.23.23.0/24 12.12.12.2 110 9 ADo 24.24.24.0/24 12.12.12.2 110 10 ADo 34.34.34.0/24 12.12.12.2 110 11 ADo 35.35.35.0/24 12.12.12.2 110 12 ADo 36.36.36.0/24 12.12.12.2 110 13 ADo 46.46.46.0/24 12.12.12.2 110 14 ADo 47.47.47.0/24 12.12.12.2 110
Sepertinya tidak perlu saya tunjukkan tabel routing dari seluruh router, Untuk lebih memastikan, kita coba lakukan ping dari R1 ke seluruh router lainnya
[admin@R1] /routing ospf network> /ping 2.2.2.2SEQ HOST SIZE TTL TIME STATUS 0 2.2.2.2 56 64 0ms sent=1 received=1 packet-loss=0% min-rtt=0ms avg-rtt=0ms max-rtt=0ms [admin@R1] /routing ospf network> /ping 3.3.3.3 SEQ HOST SIZE TTL TIME STATUS 0 3.3.3.3 56 63 2ms sent=1 received=1 packet-loss=0% min-rtt=2ms avg-rtt=2ms max-rtt=2ms [admin@R1] /routing ospf network> /ping 4.4.4.4 SEQ HOST SIZE TTL TIME STATUS 0 4.4.4.4 56 63 2ms sent=1 received=1 packet-loss=0% min-rtt=2ms avg-rtt=2ms max-rtt=2ms [admin@R1] /routing ospf network> /ping 5.5.5.5 SEQ HOST SIZE TTL TIME STATUS 0 5.5.5.5 56 62 2ms sent=1 received=1 packet-loss=0% min-rtt=2ms avg-rtt=2ms max-rtt=2ms [admin@R1] /routing ospf network> /ping 6.6.6.6 SEQ HOST SIZE TTL TIME STATUS 0 6.6.6.6 56 62 2ms sent=2 received=2 packet-loss=0% min-rtt=2ms avg-rtt=2ms max-rtt=3ms [admin@R1] /routing ospf network> /ping 7.7.7.7 SEQ HOST SIZE TTL TIME STATUS 0 7.7.7.7 56 62 2ms sent=1 received=1 packet-loss=0% min-rtt=2ms avg-rtt=2ms max-rtt=2ms
Oke R1 sudah bisa ping ke seluruh ip loopback router lain. Ini artinya konfigurasi OSPF yang kita lakukan sudah berjalan dengan baik..
Oke sampai disini dulu artikel ini, sampai ketemu di artikel selanjutnya. Selanjutnya kita akan membahas konfigurasi MPLS pada jaringan ISPF...
