   It's not true. Both side of any communication in same broadcast domain   
   must send and be able to receive with same MTU.   
      
   For example - we have network segment with one IP subnet. MTU was   
   increased to almost 9000 due to lot of NFS traffic. One host serving   
   important service is running on older machine without ability to   
   increase MTU size(we cannot replace the server too). All other   
   hosts in subnet have static route with MTU set(in linux MTU   
   comes from routing tables;) and it works well for almost 2 years.
