column BridgeId 
For CIST, Regional Root Identifier is the Bridge Identifier 
of the single bridge in a Region whose CIST Root Port is a 
Boundary Port, or the Bridge Identifier of the CIST Root 
if that is within the Region;
For MSTI,MSTI Regional Root Identifier is the Bridge 
Identifier of the MSTI Regional Root for this particular
MSTI in this MST Region;
