Abstract
In some embodiments, a method fragments a first packet into a plurality of fragments when a length of an encapsulated first packet is larger than a maximum transmission unit size. For each fragment in the plurality of fragments, fragmentation information is generated. The method encapsulates each fragment in the plurality of fragments with an outer header to form a plurality of encapsulated packets. The respective fragmentation information for each fragment is inserted in a portion of the outer header that is processed by endpoints of an overlay tunnel and not processed by a device along a path of the overlay tunnel. The plurality of encapsulated packets are sent via the overlay tunnel.
