Re: VTP Pruning vs. Allowed Vlan

Few things to consider when dealing with VTP pruning:

"Enabling VTP pruning on a VTP server enables pruning for the entire
management domain.

By default VLANs 2 through 1000 are pruning-eligible. VTP pruning does not
prune traffic from VLANs that are pruning-ineligible. VLAN 1 is always
pruning-ineligible; traffic from VLAN 1 cannot be pruned.

Enabling or disabling VTP pruning on a VTP server enables or disables VTP
pruning for the entire management domain.

Making VLANs pruning-eligible or pruning-ineligible on a switch affects
pruning-eligibility for those VLANs on that device only (not on all switches
in the VTP domain)"
