Explanation

This describes a Denial of Service (DoS) attack. By flooding a router with many simultaneously open connections, the attacker exhausts the router's connection table or processing resources, preventing it from forwarding legitimate traffic. All downstream hosts are effectively taken offline as a result. ARP redirect is a Man-in-the-Middle technique that manipulates ARP tables; it does not target router connection capacity. The attack described is resource exhaustion-based DoS, not physical tampering.
