BIG-IP Spanning-tree behavior question

However, my company boss says the pass-through mode STP behaves IN THE SAME

 

VLAN SEGMENTS.

Sorry... I don't understand this statement? Behaves in the same VLAN segments?

 

 

basically the difference between the two is that STP_MODE_TYPE_DISABLED just drops BPDU's without forwarding, and STP_MODE_TYPE_PASSTHROUGH just forwards them... But I'm not sure what your statement form your boss is trying to say... Is he saying they do the same thing? Because if you're bridging two connections back to the same VLAN they certainly don't behave the same. if you bridge with STP_MODE_TYPE_DISABLED you'll probably end up with a bridging loop...
