Figure 10: VSP 4000 as an edge router and with an additional link with ERS 8800
The SLPP PDUs generated by VSP 4000 return to the same DUT through the additional link.
After the threshold value set on the SLPP enabled ports is reached, the ports go down.
Scenario 3: VSP 4000 as a BEB connected to an edge router
In scenario 3, VSP 4000 acts as a BEB and is connected to a BayStack device. SLPP is
enabled on the UNI ports of the VSP 4000. Because the MLT ports are misconfigured, loops
can occur. For example, port 10 on BayStack is part of the MLT, but on VSP 4000 port 1/1 is
not part of the MLT, but both devices are on the same VLAN.
