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

2. 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

3. 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	-

4. Menentukan gateway / next hop
