Figure 11: VSP 4000 as a BEB connected to an edge router
In this scenario, either SLPP or RSTP/MSTP can bring the ports down.
Scenario 4: Two VSP 4000 switches acting as BEBs
In scenario 4, there are two VSP 4000 devices that act as BEBs and are connected to each
other through MLT, with two BayStack devices connected to each of the BEBs. The interface
that connects the VSP 4000 interfaces is an ISIS interface with STP disabled. SLPP is enabled
in the UNI ports of the VSP 4000. Because the link between the VSP 4000 uses ISIS interfaces,
and STP is disabled on these interfaces, STP may not be able to detect the loop.
