Thanks! Do you think I should apply hierarchical QoS to the tunnel
interface itself and then also apply the QoS preclass' to the same interface
as well? I haven't had a chance to read more about it yet. Doin' a
practice lab now and will definitely read more up on it tonight and try to
lab it up.
Thanks,
Jason
