Two questions:
1) I assume MTU path discovery has to been in enabled on each router in the pa th in order for it work correctly?!
No -- it only has to be enabled on routers with smaller outbound MTUs than inbound. A router for which all links have a 1500-byte MTU doesn't need path MTU discovery; it will never need to fragment anything. --Steve Bellovin, http://www.research.att.com/~smb
