As it does for IPv4, the Oracle® Enterprise Session Border Controller supports reassembly and fragmentation for large signaling packets when you enable IPV6 on your system. The Oracle® Enterprise Session Border Controller takes incoming fragments and stores them until it receives the first fragm...
Fragmentation and reassembly If a router receives an IP packet that is too large for the network to which the packet is being forwarded, IP fragments the original packet into smaller packets that fit on the downstream network. When the packets arrive at their final destination, IP on the desti...

Attackers abuse IP fragmentation to evade security controls and exploit vulnerable systems: Disrupt reassembly – Sends malformed fragments that cause errors or crashes during the reassembly process, resulting in denial-of-service. Bypass firewalls – Firewall rules are avoided by sending attacks in frag...
Fragmentation and Reassembly If a router receives an IPv4 packet that is too large for the network segment on which the packet is being forwarded, IPv4 on the router fragments the original packet into smaller packets that fit on the forwarding network segment. When the packets arrive at their ...

Fragmentation is removed from the intermediate node. Fragmentation and reassembly are performed by the source and destination, respectively. The path maximum transmission unit (PMTU) mechanism is used to determine the MTU of a path. The fixed-length IPv6 header is defined to facilitate fast hardware...
