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

[Carlo]

 Can you ping thru to the other side? if yes then check your MTU, a MTU of 1500 will cause a lot of problems if the packets are going thru a firewall or something that doesn't like its packets fragmented. bump it up to 1600 and see what happens
