CPT-VLSM

Untuk tree VLSM dibuatkan seperti berikut ini:

Tabel berikut menampilkan subnet dan jumlah IP untuk mendapatkan netmask tiap subnet:

Subnet Jumlah IP Netmask
A1 721 /22
A2 252 /24
A3 2 /30
A4 521 /22
A5 13 /28
A6 502 /23
A7 2 /30
A8 1001 /22
A9 2 /30
A10 701 /22
A11 2 /30
A12 101 /25
A13 2021 /21
TOTAL 5841 /19

Dalam perhitungan NID dan Broadcast, disini digunakan dari IP terbesar terlebih dahulu. Dari hasil perhitungan didapatlah:

UML-CIDR

Untuk tree CIDR dibuatkan seperti berikut ini:

Dari hasil perhitungan NID dan Broadcast, didapatlah:

Untuk implementasi pada UML maka dibuatkan topologi dengan script sebagai berikut.

uml_switch -unix switch1 > /dev/null < /dev/null &
uml_switch -unix switch13 > /dev/null < /dev/null &
uml_switch -unix switch15 > /dev/null < /dev/null &

Pada file /etc/sysctl.conf di setiap router yaitu pada UML SURABAYA, PASURUAN, PROBOLINGGO, BATU, KEDIRI, MADIUN, BLITAR dibuat agar dapat melakukan packet forwarding IPv4 dengan melakukan uncomment pada net.ipv4.forward=1 sebagai berikut.

Untuk melakukan pembagian IP pada setiap Host maka dilakukan konfigurasi pada /etc/network/interfaces tiap host dan routing untuk setiap router sebagai berikut.
