intervlan routing adalah membuat routng antar vlan supaya bisa saling berhubungan dengan menambahkan sebuah router.
mengapa perlu vlan ?
karena apabila semuanya meggunakan satu switch, apabila semuanya mengakses jaringan maka akan terjadi bounce / flooding pada network dan otomatis ferorma network akan menurun.

langsung saja ke konfig intervlan routing, seperti biasa kita menggunakan packet tracer untuk virtual routingnya..

pengaturanya sama kayak switch 0, karena konsepnya ssama dan interfacenya saya set sama jg

Setelah itu buat IP di Pc0 dan Pc1 untuk vlan kantor
PC0
ip 192.168.1.2
subnet mask 255.255.255.0
ip gateway 192.168.1.1

PC1
ip 192.168.1.3
subnet mask 255.255.255.0
ip gateway 192.168.1.1

Dan juga buat IP di Pc2 dan Pc3 untuk vlan lab
PC2
ip 192.168.2.2
subnet mask 255.255.255.0
ip gateway 192.168.2.1

PC3
ip 192.168.2.3
subnet mask 255.255.255.0
ip gateway 192.168.2.1

dan coba ping dari pc1 ke pc3...
treeengggg...... !!! CONNECTED !!!

dan sekarang bukan masalah lagi membuat vlan saling berhubungan..

terima kasih semoga membantu !!!!
