Meanwhile I have made progress. But from the start: An MSTP region is defined as: * Format Selector * Configuration Name * Revision ID * VLAN <-> SID hash
Consequently, I thought modifying one of those parameters was enough for a new region to be created. While that seems true as far as MSTP itself is concerned, Netsight Topology Manager does not seem to like it when you only change the VLAN<->SID mapping but leave the rest untouched, i.e. same configuration name and everything. It will show you two bridges that are both CIST region root as well as designated root in one diagram. If you indeed give the new region another configuration name, then you can select the region+instance you wish to view from the dialog that shows when you select "multiple spanning tree" from the menu. All that does not belong to that region is then shown with dotted lines. --- To unsubscribe from enterasys, send email to [email protected] with the body: unsubscribe enterasys [email protected]
