I wouldn't say it is good news.
Lots of people smoke and drink too, it doesn't make it healthy.
Long term you want to stop fragmenting.

the good news is, I'm the provider network and it's my backbone.

the bad news is, I have a mixed environment, Foundry/Brocade and Cisco.

Much appreciated, Eric

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".
