VTP Source 1: “Version-dependent transparent mode; transparent mode no longer checks domain name.This enables support of more than one domain across a transparent domain.” Some of the newer documentation states to the contrary.

Therefore VTP pruning can be applied only from VLAN 2 to 1001.

Reference: Client mode we cannot create VLAN and Switch1 does not have any trunk links so it cannot receive any VTP updates.

Reference: switches are running VTPv1 so they cannot share the MST configuration with each other (only VTPv3 supports MST).

Therefore in order to share the same MST with DSW2, DSW1 must be manually configured with the same region name, revision number and VLAN-to-instance mapping with DSW2.
