Since Map-Requets are small, it is unlikely that an MTU violation will occur for a Map-Request forwarded on the ALT. But if the case did arise, there would be fragmentation and reassembly at each GRE end-point since a Map-Request, when sent from one ALT node to another, is encapsulated in a GRE tunnel header.
