MST Region
A set of LANs and MST Bridges physically connected
via Ports on those MST Bridges, where each LAN’s
CIST Designated Bridge is an MST Bridge, and each
Port is either the Designated Port on one of the LANs,
or else a non-Designated Port of a MST Bridge that is
connected to one of the LANs, whose MCID matches
exactly the MCID of the Designated Bridge of that
LAN.
NOTE—It follows from this definition that the MCID
is the same for all LANs and Ports in the Region, and
that the set of MST Bridges in the region are
interconnected by the LANs.
SST Bridge
Single Spanning Tree
Bridge
A Bridge capable of supporting only a single spanning
tree, the CST. The single spanning tree may be
supported by the Spanning Tree Algorithm and
Protocol (STP) or by the Rapid Spanning Tree
Algorithm and Protocol (RSTP).
