Cisco : Static Routing

Static routing ialah sebuah konsep jaringan yang penting yang melibatkan konfigurasi rute secara manual pada router. Rute ini mengarahkan perutean ke tujuan jaringan tertentu dan memiliki administrative distance (AD) 1, yang menjadikannya sangat tepercaya, nomor dua setelah rute yang terhubung secara langsung AD 0.

R1(config)#ip route [network-address] [subnet-mask] ([next-hop-ip] [exit-int])

• network-address: Network Tujuan
• subnet-mask: subnet mask network tujuan
• next-hop-ip: IP address dari next hop network tujuan.
• exit-int: interface dari next hop network tujuan.

• Default Static Route

R1(config)#ip route 0.0.0.0 0.0.0.0 ([next-hop-ip] [exit-int])

Default route statis digunakan ketika tidak ada route lain yang cocok dengan alamat IP tujuan. Ini akan menjadi rute pilihan terakhir.

• Floating static route

R1(config)#ip route [network-address] [subnet-mask] ([next-hop-ip] [exit-int]) [AD]

Floating static route adalah rute cadangan dengan administrative distance yang lebih tinggi, sehingga membuatnya jadi rute cadangan jika rute utama gagal.
