Pogledajte sličan scenarij s Quagga routerom.

1. NAČELAN SLUČAJ

Korištena verzija Vyatte: VC 2.0, 20.veljače 2007.
Testirat ćemo u ovom trećem primjeru okruženje srednje razine složenosti gdje su dvije radne površine zajedno povezane s dva OPSF područja, jedno OSPF područje je označeno kao stub područje. Ostale dalje izlistane Vyatta funkcionalnosti testirane su u isto vrijeme.

Vyatta A router i Layer 3 Switch locirani su u stub području. Oni imaju OPSF rute unutar (O) i rute među područjima (OIA) u svojim routing tablicama ali nemaju vanjsku OSPF rutu. Da bi se rutirale te vanjske OPSF mreže kao 10.200.1.4 (pogledajte sljedeći stavak), tu je podrazumijevana OSPF ruta ka graničnom routeru (Vyatta A router) na routerima unutar područja 1. Vyatta A je granični router zato jer je u području 0 ili backbone područje i u području 1.

U svrhu proučavanja ovog slučaja, statična ruta 10.200.1.4 je redistribuirana u OSPF na Vyatta B router da "umjetno" stvori vanjsku OPSF mrežu označenu kao OE2. Zbog stub područja, ova mreža ne bi trebala biti proširena na Vyatta A router i na Layer 3 Switch.

Molimo, budite svijesni da Vyatta ntp sinkronizacija i postavke dhcp releja ne rade na Vyatti VC2.
