[c-nsp] mpls ip creating traffic disturbance(s)

[Eric A Louie]

No, the MTU was set to 1500.  I have been informed that the tags create a few 
bytes of overhead that would cause problems in  packets where DF was set.  But 
even traffic that didn't traverse the mpls ip link was (seemingly) affected

 Much appreciated, Eric

Did you change system or link MTU?
