I'm currently learning a bit about Cisco switch configuration and VLAN configuration, specifically VTP. Reading on Cisco's site, the feature of VLAN pruning appears to not be used on a switch/VTP domain/VLAN by default. From what they give:
All unknown unicasts and broadcasts in a VLAN are flooded over the entire VLAN. All switches in the network receive all broadcasts, even in situations in which few users are connected in that VLAN. VTP pruning is a feature that you use in order to eliminate or prune this unnecessary traffic.
Does it pose a specific drawback, such as certain types of traffic that may not reach their destination or higher memory use/autoconfiguration time, that makes it unfit for use in some configurations/networks?
