1. CASO STUDIATO

Vyatta versione: VC 2.2 Aug 30, 2007
In questo caso studieremo la standardizzata routing redundancy protocol chiamata VRRP (Virtual Routing Redundancy Protocol). È basata sulla Cisco redundancy protocol chiamata HSRP ed è l’unico modo di avere la ridundanza tra routers di differenti produttori .
Il router che ha il più alto VRRP diventa automaticamente il master . Il suo MAC address simile a 00-00-5E-00-01-XX corrisponde al virtual VRRP IP address.
Per maggiori informazioni sul protocollo VRRP, visitate l’eccellente VRRP Wikipedia pagina.
