I think this configuration can fulfill the task.

vtp mode transparent
interface FastEthernet0/23
 switchport trunk encapsulation isl
 switchport mode trunk
 switchport nonegotiate
interface FastEthernet0/24
 switchport trunk encapsulation isl
 switchport mode trunk
 switchport nonegotiate

=====================
