LANs exist, spanning tree can be implemented at each

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.

ciscoproprietary so it use isl encapsulation for trunking.
