in a broadcast domain - which is defined in a switching environment (though
not always) by a VLAN. Thus spanning tree reduces this potential per VLAN. I
am sure there a myriad of other reasons..:)
VTP: one of the reasons is bandwidth - your access-links (that is links
between switches ) may become overburdened when you are forwarding traffic
from lots of VLANs over this trunk/access-link - this is more of a problem
when you don't need to forward some traffic over this link ie. the switches
on the receiving end do not have ports that are members of any of the
VLANs - by using VTP you can remove or 'prune' those VLAN's that the
receiving switch does not service.
