That was the first thing I thought of, but the 4700 doesn't have enough
memory to support IOS version 12, so it's running 11.3....The broadcast
keyword doesn't work in 11.3.....Does it matter if the subinterface is
point-to-point or multipoint? I'm using point-to-point (that seemed
logical), but I'm not too comfortable with non-LANE ATM inplementations.
Thanks,
Jack
