Explanation

Key Benefits of VTP Version 3 Much work has gone into improving the usability of VTP version 3 in three major areas: The new version of VTP offers better administrative control over which device is allowed to update other devices' view of the VLAN topology. The chance of unintended and disruptive changes is significantly reduced, and availability is increased. The reduced risk of unintended changes will ease the change process and help speed deployment. Functionality for the VLAN environment has been significantly expanded. Two enhancements are most beneficial for today's networks: ?In addition to supporting the earlier ISL VLAN range from 1 to 1001, the new version supports the whole IEEE 802.1Q VLAN range up to 4095. ?In addition to supporting the concept of normal VLANs, VTP version 3 can transfer information regarding Private VLAN (PVLAN) structures. The third area of major improvement is support for databases other than VLAN (for example, Brief Background on VTP Version 1 and VTP Version 2 VTP version 1 was developed when only 1k VLANs where available for configuration. A tight internal coupling of the VLAN implementation, the VLAN pruning feature, and the VTP function itself offered an efficient means of implementation. It has proved in the field to reliably support Ethernet, Token Ring, and FDDI networks via VTP. The use of consistent VLAN naming was a requirement for successful use of VMPS (Vlan Membership Policy Server). VTP ensures the consistency of VLAN names across the VTP domain. Most VMPS implementations are likely to be migrated to a newer, more flexible and feature-rich method. To add support for Token Ring, VTP version 1 was enhanced and called VTP version 2. Certain other minor changes and enhancements were also added at this time. The functional base in VTP version 3 is left unchanged from VTP version 2, so backward compatibility is built in. It is possible, on a per link basis, to automatically discover and support VTP version 2 devices. VTP version 3 adds a number of enhancements to VTP version 1 and VTP version 2: Support for a structured and secure VLAN environment (Private VLAN, or PVLAN) Support for up Feature enhancement beyond support for a single database or VTP instance Protection from unintended database overrides during insertion of new switches Option of clear text or hidden password protection Configuration option on a per port base instead of only a global scheme Optimized resource handling and more efficient transfer of information These new requirements made a new code foundation necessary. The design goal was to make VTP version 3 a versatile vehicle. This was not only for the task of transferring a VLAN DB but also for transferring other databases-for example, the MST database.
