DHCP en routage inter vlanFermé

Question

Bonjour à tous. Actuellement, en cours nous travaillons sur le routage intervlan.
Notre professeur nous demande de trouver comment faire un dhcp malgré les vlan. ma topologie réseau est comme tel:
-3 pc sur 3 vlan différents,
-1 serveur encore sur un vlan différent,
le tout relié a un routeur Cisco générique.
J'ai d'abord essayé avec dhcp help, mon prof m'a dit qu'il y avais de l'idée mais n'a pas daigné m'aiguiller plus.
De plus j'ai cherché sur le forum mais rien ne correspondait à l'infrastructure que j'ai.
Merci d'avance pour votre aide.
