When a router receives a packet with a TTL (Time-to-Live) value of 1, it means that the packet has already traveled through one network and has been processed by one router. Since the TTL value indicates the maximum number of hops (or routers) the packet can take before being discarded, the router receiving the packet with a TTL of 1 has no other choice but to drop the packet to avoid network congestion and prevent routing loops.
