While putting tcp header compression in PASSIVE mode on BOTH sides of the
Frame Relay interface, compression was still occuring. I was under the
impression that one side had to be active and on had to be passive. If both
sides are waiting for an compress packet in passive mode, they will never
receive one. But the output shows different. If anyone can provide some
insight on this I will be greatful.
