Not every device along the path can handle fragmentation. Fragmentation happens in thenetwork layerof theOSI model, as this layer is responsible for dividing the datagram received from thetransport layerinto pieces. It occurs primarily in arouterorswitchwith Layer 3 capabilities and the source device...

Data structures, a method, and an associated transmission system for IP fragmentation and IP reassembly on network processors in order to minimize memory allocation requirements. Frame data for IP fra
If VFR is manually enabled, regardless of whether it is enabled by features such as NAT and Cisco IOS XE Firewall, the ip virtual-reassembly [-out] command is displayed in the output of the show running-config command. VFR Disablement You can disable virtual fragmentation r...
Fragmentation and Reassembly for RADIUS When persistence is based on a RADIUS attribute within the UDP packet, it is critical that the load balancer reassembles the IP fragments in order for the load balancer to make the correct PSN forwarding decision. Otherwise, large RADIUS pa...
an IP datagram is the unit of end-to-end transmission at the IP layer (before fragmentation and after reassembly), and a packet is the unit of data passed between the IP layer and the link layer. A packet can be a complete IP datagram or a fragment of an IP datagram. ...
