Options
1) Ask the provider if they have any traffic engineering communities
available. Many of the large ones offer some.
2) Use BGP MED to influence the output path (works in most cases).
3) If that fails, use as-path pre-pending to influence the output path from
the provider towards you.

If you don't exceed the MTU ever then it shouldn't matter, but unless
the MTUs are above what the protocol can handle on a specific link you
probably will. Most commonly this happens on DSL links using PPPoE (the

My question was actually prompted by an issue that comes up with

Not really, but given the bursty nature of IP traffic, that's a very
