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)

Opret virtuel router

Her oprettes et routing instance af typen virtual router

Tildel interfaces

Her tildeles 2 logiske tunnel interfaces til routeren P1

[edit routing-instances P1]
rael@SRX240# <input>set interface lt0/0/0.1</input>

[edit routing-instances P1]
rael@SRX240# <input>set interface lt0/0/0.2</input>

Verificer

P2 er også oprettet og P1 pringer P2 for at kontrollere forbindelserne

[edit routing-instances P1]
rael@SRX240# show
instance-type virtual-router;
interface lt-0/0/0.1;
interface lt-0/0/0.2;
