Routing dengan metode VLSM

Langkah – Langkah:
  1. Menghitung jumlah host yang digunakan
N1 + N2 + N3 + N4 + N5 + N6 + N7 + N8 + N9 = 16+32+8+4+32+4+4+4+4=108 host
  1. Menentukan net prefiks dan alokasi IP
N1 = 14 | 4 bit -> 192.168.1.0 /28
N2 = 28 | 5 bit -> 192.168.1.16 /27
N3 = 7 | 3 bit -> 192.168.1.48 /29
N4 = 2 | 2 bit -> 192.168.1.56 /30
N5 = 28 | 5 bit -> 192.168.1.60 /27
N6 = 2 | 2 bit -> 192.168.1.92 /30
N7 = 2 | 2 bit -> 192.168.1.96 /30
N8 = 2 | 2 bit -> 192.168.1.100 /30
N9 = 2 | 2 bit -> 192.168.1.104 /30
  1. Menentukan Nilai Interface
Router e0 e1 e2
R1 192.168.1.1 192.168.1.101 192.168.1.93
R2 192.168.1.94 192.168.1.97 192.168.1.17
R3 192.168.1.98 192.168.1.49 -
R4 192.168.1.102 192.168.1.57 192.168.1.105
R5 192.168.1.106 192.168.1.61 -

  1. Menentukan gateway / next hop

Network R1 R2 R3 R4 R5
N1 direct 192.168.1.93 192.168.1.97 192.168.1.101 192.168.1.105
N2 192.168.1.94 direct 192.168.1.97 192.168.1.101 192.168.1.105
N3 192.168.1.94 192.168.1.98 direct 192.168.1.101 192.168.1.105
N4 192.168.1.102 192.168.1.93 192.168.1.97 192.168.1.direct 192.168.1.105
N5 192.168.1.102 192.168.1.93 192.168.1.97 192.168.1.106 direct
N6 direct direct 192.168.1.97 192.168.1.101 192.168.1.105
N7 192.168.1.94 direct direct 192.168.1.101 192.168.1.105
N8 direct 192.168.1.93 192.168.1.97 direct 192.168.1.105
N9 192.168.1.102 192.168.1.93 192.168.1.97 direct direct
