Re: Stateful Ethernet Bridging and it's effect on overall Internet topology.

I agree, however there are some implementations of this type of bridging that 'routing' would not be a good substitute for. Say mangling traffic going outbound for compression purposes (A La Redline (Yes I know redline does proxying and not bridging)). I guess my best question would be, is there a solution to the problem. Maybe a possible way of bridging the traffic without polluting the world with unnecessary broadcasts of MAC addresses and over-head ethernet frames. (Is there a way to strip that garbage from the outbound traffic generated by the bridge).

And I deployed 100s of these into the facility as a means to control overall traffic. Would these transparent bridges be detrimental in any way to the rest of the internet. I understand that since they are re-transmitting data that the possibility of their MAC addresses popping up every time a machine behind it pops up could be an issue when doing network monitoring. But I'd just like to know what everyone thinks about such products.
