Lab.14 CCNA Cara konfigurasi Switch Virtual Interface - Untuk menghubugnkan antar VLAN, selain menggunakan Router on a Stick, juga bisa menggunakan Switch Virtual Interface. Pada packet tracer, menggunakan Multi Layer Switch 3560. Defaultnya setiap switch mempunyai template masing-masing, tergantung kemampuan switch. Template tersebut dinamakan Switch Database Manager (SDM).
Untuk melakukan routing Layer 3 di perangkat Layer 2, diperlukan enable fitur L3 pada perangkat Layer 2. Fitur Switch Database Manager (SDM) mode lanbase-routing/routing harus dienble untuk dapat melakukan routing di switch.
Pada topologi diatas MLS1 berfungsi meroutingkan PC0 yang berada di vlan10 dan PC1 yang berada di vlan20 menuju R1. Lab dikatakan berhasil jika PC0 dapat melakukan ping pada R1. Berikut konfigurasi lengkapnya :
Cek mode Switch Database Management, untuk mampu melakukan lab ini harus dirubah menjadi routing/lan-base routing
