I am curious if there is some sort of igmp or other form of message that would reliably detect if a switch had a bridge on it. How could deviceA detect deviceC was a bridge in this case?
Hi Dave, Start with precision in language. An ethernet switch is one form of ethernet bridge although the reverse is not necessarily true. So, a switch is always a bridge by definition. Q.E.D.
From what you've posted, you don't want to detect the difference between a switch and a bridge, you want to detect the difference between a wired and wireless segment segment in the network. Is that correct? Any wireless link or just radio? Any radio link or just 802.11 wifi? Are you just trying to detect stations behind wireless or do you want to identify segments that are carried over wireless?
