Labo Frame-Relay 1 : Configuration basique
Dans cette configuration de base, un PVC est créé entre RA1 et RA2, le type de message LMI est Cisco par défaut. Puisqu'une interface physique est par défaut une interface multipoint, Inverse ARP est activé (ce ne sera pas le cas pour les interfaces point à point). IP Split Horizon est désactivé sur les interfaces configurées en encapsulation Frame-Relay, ainsi les mises à jour de routage peuvent entrer et sortir de la même interface. Les routeurs apprennent les DLCI dont ils ont besoin à partir du Switch Frame-Relay via des mises à jour LMI. Inverse ARP est appliqué sur l'adresse IP distante et un mapping des DLCI locaux est créé avec la correspondance des adresses IP à joindre.
