Hub-n-Spoke Using Frame-Relay Point-to-Point

Configuration « Hub and Spoke » en mode « point to point »

  • l’encapsulation frame relay est spécifiée au niveau de l’interface physique
  • Une sous interface de type « point to point » est créé pour chaque DLCI
  • l’utilisation de « frame-relay map » n’est plus nécessaire

Remarque :

  • « inverse-arp » est désactivé automatiquement lors de l’utilisation d’interfaces point to point
