EIGRP
Enhanced Interior Gateway Routing Protocol (EIGRP) is a Cisco proprietary routing protocol based on the Diffusing Update Algorithm (DUAL). It provides fast convergence, low network overhead, and scalability. EIGRP works best when all devices in the network are Cisco, as it requires certain features that other vendors may not have. It is used in large-scale, mission-critical networks to optimize routing paths.

Teardrop Attacks
In order to detect teardrop attacks, administrators should look for large numbers of packets containing identical fragment lengths and offsets. Additionally, any unusually large numbers of fragmented packets should be investigated as these could be indicative of an attack.
Organizations can protect against teardrop attacks by ensuring their systems are up to date with the latest security patches, configuring firewalls to block incoming packets with suspicious lengths and offsets, and deploying Intrusion Detection Systems (IDS) and Intrusion Prevention Systems (IPS) to monitor traffic and alert administrators when potential threats are detected.
