This allows for much easier administration when managing larger scale deployments with multiple networks involved instead of having them isolated from each other in different segments due lack of proper connectivity between them without requiring manual intervention every time a connection needs established between two networks which could become difficult quickly if working with a large scale deployment over time as new devices need added or removed from various segments within it regularly over time due normal maintenance or changes being made periodically over its lifespan while still allowing full communication between all parts involved at once regardless what segment they may be placed in even after those changes have taken place since connectivity remains intact even after those changes have been applied due its lack requirement for manual intervention when those changes take place after initial setup has already been completed since they remain connected already before any adjustments needing made instead requiring new configurations established manually each time some sort adjustment needs applied when those changes take place which would become tedious very quickly depending size scale deployment was dealing with its maintenance over time due its potential expand or contract periodically depending situation required its use at given point time since
