In Ethernet switched environments where multiple Virtual
LANs exist, spanning tree can be implemented at each
vlan . and it is named as per VLAN spanning tree (PVST and
PVST+, which is the default protocol used by Cisco
switches). Both PVST and PVST+ protocols are Cisco
proprietary protocols.Since PVST treats each VLAN as a
separate network, it has the ability to load balance
traffic (at layer-2) by forwarding some VLANs on one trunk
and other Vlans on another trunk without causing a Spanning
Tree loop.
here one point is noted that scinse it is a
ciscoproprietary so it use isl encapsulation for trunking.

if you want to know that how to do that then here i canot
expalin how toconfigure that pvst+
