Thank you for all the feedback.
I have changed all switches to vtp version 2 but still no propagation
through the transparent switch. this seems in line with the explanation from
Oletu.
BTW I managed to have it working anyway by enabling 'l2protocol-tunnel vtp'
on the trunk port of the transparent switch :-)
Thanks,
Bit.
PS: this is my version
C3750 Software (C3750-ADVIPSERVICESK9-M), Version 12.2(25)SEE
