Hello, Didn't mean anything - just some information in case you guys not just study but doing work for your company also. And like John said, I was curious to see if you could do broadcast over the tunnel since when talk about GRE, mostly it could implement multicast and not a mention of broadcast. There's no right or wrong - just information. Didn't mean to upset anyone Guess I am a bit different, I don't want to take the ccie lab any more :) too tired of that - just want to learn more about tech in general 12.2.15T5 is fine - we were using that T train anyway, just ran across some bugs that prompt us to go with 12.3.1. If you are in the vpn business, then this 12.3 code is quite good since it supports vam2 card...etc To me personally, those kind of questions sometime good - since those could be asked by the customers

[7:72738] Fred, A few years ago this list was opened up to questions and discussions that aren't necessarily related to certification. In fact, discussions don't even have to be Cisco-related, although they usually are. You'll quite often see stuff like this around here, and many times people simply want to know if something can be done, not whether it's a good idea for it to be done. :-) I have my doubts that this could be configured in such a way as to be reliable and stable, but who knows. I even gave a suggestion earlier that I now think won't work. I'm too tired at the moment to try it out, though.
