 To be honest I had no problem understanding this draft. I am far from the
technical guru of switches as a few of you can testify. Yet, this draft
was very clear to me. I understood that a switch could do four possible
things with a FGL packet.
1. It understands it, does what the packet says, and passes it on
2. It doesn't understand it, but passes it on to another switch that does
3. It drops the packet because it doesn't understand it
4. It barfs

To me number one was an FGL capable switch. Number two was an FGL safe
switch.  Number three isn't useful and won't be considered safe in getting
the packet across the network. Number four was not safe under any
condition.

I wish to thank the writers for taking the time to include enough
information such that someone like me can read these specifications and
understand them. I know it takes a lot more of your time to do so and I
really appreciate it.
thanks again
