Chapter 7. VLAN Trunking Protocol


This chapter covers the following topics that you need to master for the CCNP BCMSN exam:

  • VLAN Trunking Protocol This section presents Cisco VLAN Trunking Protocol (VTP) for VLAN management in a campus network.

  • VTP Configuration This section covers the Catalyst switch commands used to configure VTP.

  • VTP Pruning This section details traffic management by pruning within VTP domains, along with the commands needed for configuration.

  • Troubleshooting VTP This section gives a brief summary of things to consider and commands to use when VTP is not operating properly.

When VLANs are defined and used on switches throughout an enterprise or campus network, the administrative overhead easily can increase. Using the VLAN Trunking Protocol (VTP) makes VLAN administration more organized and manageable. This chapter covers VTP and its configuration.

A similar standards-based VLAN-management protocol for IEEE 802.1q trunks is called GARP VLAN Registration Protocol (GVRP). The GARP and GVRP protocols are defined in the IEEE 802.1D and 802.1q (clause 11) standards, respectively. At press time, GVRP was not supported in any of the Cisco IOS Softwarebased Catalyst switches. Therefore, it is not covered in this text or in the BCMSN course.
