  10. Frame Tagging and Encapsulation Methods

  11. VTP Benefits

  12. VTP Concepts The role of VTP is to maintain VLAN configuration consistency across a common network administration domain.

  13. VTP Modes • Server • Client • Transparent

  14. VTP Mode Comparison

  15. VTP Operation

  16. VTP Implementation • There are two types of VTP advertisements: • Requests from clients that want information at bootup • Responses from servers • There are three types of VTP messages: • Advertisement requests • Summary advertisements • Subset advertisements

  17. VTP Basic Configuration Steps • Determine the version number • Choose the domain • Choose the VTP mode • Password protect the domain

  18. Inter-VLAN Routing

  19. Inter-VLAN Issues and Solutions Two of the most common issues that arise in a multiple-VLAN environment are as follows: • The need for end-user devices to reach nonlocal hosts • The need for hosts on different VLANs to communicate

  20. Router on a Stick

  21. Physical and Logical Interfaces

  22. Dividing Physical Interfaces into Subinterfaces

  23. Configuring Inter-VLAN Routing
