Which spanning tree protocol is preferred PVST or rapid-PVST and why?

[Rizwan]

I have WS-C2960G-24TC-L and Cisco 3750G switches, I have option to configure PVST spanning tree or rapid-pvst. Please let me know which is better and why? also send me some document explaining both protocols in detail.

Hi,

If this is a new network or a complete network redisign you should go for
RAPID-PVST.

This is equal to the IEEE recommendation 802.1W

Provides faster convergence and STP state changes.

This link gives a simple intoduction and how to
configure

Look further down in the link at the conclusion summary too.

As Alex has noted, normally rapid-PVST should be preferred.

Depending on needs (and device support), MST might be better yet.
