Thanks Gert - It's because we are purchasing inter-pop links from other 
carriers(And there supported MTU's varies dramatically)...in this instance our 
PE's "agreed" on 1900'odd MSS, but we were only able to get ~1544.....On the 
links we control, it's all 9100.....and we tweak as needed with carrier 
supplied links.

Cheers.
