the other day i was watching the firewall design and deployment session of cisco networkers 2009 with mason harris. one of the topics he was talking about is how the same mac-address is assigned to shared interfaces in multiple context deployment with the ASA, he said that a problem could arise since "switches dont like that", according to him switches dont like to see the same mac-address assigned to multple contexts. Im trying to figure out what is exactly the problem with the switch connected to an ASA with multiple context but i havent found a good reason of why there is an issue with this; i know there are issues when internal traffic is trying to reach external traffic, for example the internet, and there is not static or xlate entries available for the classifer to make a decision about with context should get the traffic.
I would like to find an answer for this since im working on my SNAF exam right now, or maybe i misunderstood something about what he said.
thanks all for your replies.
