We enabled VTP and started using it shortly after our new infrastructure was put in-approx 1-1/2 years ago.
However we did not enable pruning.
Would enabling in now cause any problems. We have approx 25 VLans that really at this point aren't being used to any great extent, some more than others, however we are starting to subnet our network down more and I am wondering if turning on pruning would cause any issues when first turned on?
Everything I read says it's a good idea but nothing explains what happens when first turned on.
