Routeur Cisco 3745 Switch 2950

Bonjour,

Nous disposons d'un routeur Cisco 3745 et d'un switch Cisco 2950. Nous souhaitons les configurer de manière à faire communiquer 4 VLANs:
- VLAN1 Management
- VLAN2 Wifi
- VLAN3 Serveur
- VLAN4 Client

De plus, nous souhaitons activer le VTP entre ces deux composants, Routeur en VTP server et switch en VTP Client.
On a donc placé les deux éléments dans le même domaine VTP, crée le lien TRUNK acceptant les 4 VLANs sur le switch et créé les sous interfaces sur le routeur permettant la communication des différents VLAN entre le Routeur et le switch.

Cependant, le VTP ne fonctionne pas, c'est à dire que la configuration effectuée sur le routeur concernant les VLAN ne se transmet pas au switch.

Question : Ou faisons-nous une erreur?

Voici nos configurations
