Re: [mpls-linux-general] Sending heavy traffic via MPLS

[James R. L. <jl...@mi...>]

If I remember correctly 'scp' uses a TCP session.  There has been a long
standing issue with using TCP (path discovery) and MPLS.  You could try to
setting the MTU of the host interface to something less then 1496 and see
if that helps a all.
