VTP pruning and Trunk interfaces
Dear GS,
I am working on a LAB exercise. Sw1 is the VTP server and Sw2, sw3, sw4 are clients. I have configured the trunk links between Sw1 - Sw2, sw1- sw3, Sw1 - sw4 and have allowed all the VLANs. Then there was a task to configure switchport connecting to Router 6 as dot1q trunk on switch 2. Followed was a task for enabling VTP pruning.
I was able to get the desired result for pruning on the links between sw1 - SW3 and SW1 - SW4, But in the link between SW1-SW2 the pruning was not happening and all the vlans were allowed eventhough there were some vlans which are not locally assigned.
But once I removed the dot1q trunk on the switch2 going to one of the router, I was able to saw the desired pruning result.
But as per the LAB solutions, this was not the case.
can some body tell me what went wrong?
with thanks sathappan
