[c-nsp] mpls and etherchannel

     I have 2x 200mbps microwave links connecting switch 'a' to switch 
'b'. I have a port-channel configured and I currently get an acceptable 
split of traffic based on source / destination address mac hash.

     I am now looking to deploy mpls in this portion of the network and 
I am concerned that I will no longer get much of any traffic split since 
the mac address of the frames will largely be the mpls sender / receiver 
and not much of any diversity here. I have read that the solutions would 
be ecmp, but then I am worried about the possibility of packet 
re-ordering...? The links themselves are direct point to point and I 
don't anticipate that one would be any faster or slower than the other, 
I just don't know what to expect or if there is something else I would 
look at for this situation?
