Hello.. We have to provide a point-to-point Metro-Fiber link with 1600 MTU (1550 for Customer & 50 Bytes for our own use i.e. to compensate for overheads such as L2TP & Q-in-Q). Issue is that currently the available Metro-Fiber link only supports 1500 MTU and the available MTU to Customer is less than 1500 because of the overheads mentioned above which is not acceptable to Customer. (Question) While we have to perform Fragmentation, is it possible to hide from Customer that actually Fragmentation is being done & Customer can be provided 1550 MTU (such that when it performs Ping test with -f, it is unable to find out that available MTU is less than 1550). Heard from friends that Cisco offers such solution, hope somebody could help.
