Virtual Router JUNOS

Beskrivelse

Virtual Routers bruges på Juniper Udstyr til at lave total adskildte netværk inden i den samme kasse. Det er en af de forkskellige typer af Routing Instance JUNOS understøtter.
I de forskellige Virtuelle routere vil routnings tabel, interfaces og tabeller være helt adskidlte.

Følgende skal konfigureres for at bruge virtuelle routere:

1. Opret en virtuel router
2. Tildel interfaces til den virtuelle router
3. Konfigurer routing options for den virtuelle router(optional)

Her tildeles 2 logiske tunnel interfaces til routeren P1

[edit routing-instances P1]
rael@SRX240# <input>set interface lt0/0/1.1</input>

[edit routing-instances P1]
rael@SRX240# <input>set interface lt0/0/3.2</input>

Verificer

[edit routing-instances P1]
