Mstp Basic Concepts - HP 3100 Series Configuration Manual

•
MSTP prunes a loop network into a loop-free tree, which avoids proliferation and endless
cycling of packets in a loop network. In addition, it supports load balancing of VLAN data by
providing multiple redundant paths for data forwarding.
