any change if you increase the WAN mtu (FR) on both sides to say 1600?
We cannot fragment frames with direct encap and with ethernet there is no
way to tell end stations to send only up to a maximum size. As a
consequence for ethernet attached end devices IOS checks to have a WAN mtu
bigger than the max frame size allowed on ethernet.
