VTP Mode Best Practices
Some environments still deploy VTP server/client mode, while
others stick with transparent mode. It is recommended that you configure VTP for
transparent mode for a number of reasons, aside from the revision number issue.
If an engineer accidentally erases a VLAN, the switch through the VTP mechanism
will propagate that information to the rest of the domain. In addition, VTP
server/client mode currently only supports VLANs 1-1024. The extended VLAN
range, 1024-4096, requires the switch to be configured in transparent mode. The
rule of thumb is keep everything simple, because in the long run it can save
time and money.
Thus far, the discussion throughout this chapter has been on
theory and design considerations. The following section introduces some
rudimentary examples on configuring the aforementioned topics. Cisco provides
quite a bit of information on its site about how to configure various protocols,
features, and so forth. Chapter 5,
"Using Catalyst Software," is exclusively dedicated to providing configuration
examples that will familiarize the reader on the more common configurations seen
in the enterprise network.
