This is very common practice and practically everyone does it.
Usually if you have your own backbone you enlarge the backbone packet size though.
Sometimes that isn't an option due to provider switches in the path.

I just put in this command on my upstream interfaces to help my mpls network pass traffic - that is, my effort to eliminate fragmentation in my backbone.

Is anyone else using this method of "mtu control"?  I need some support - my CEO is asking why I have to do this, and who else does it, and is it a common practice, etc, so I'm looking for evidence, more than just "The Cisco TAC told me to do it".


 Much appreciated, Eric
