Only the IP portion of the packet is dropped, but the TCP portion continues to the last router.
The routing protocols will carry the TCP information to the previous-hop router, which sends a reverse notification to the source.
The routing protocols, such as RIP, are connection oriented and will contact the source host.
The destination host is expecting the packet and will send a request if it does not arrive.
The IP header contains the source address so that the packet can be returned by the router that receives the packet when the TTL is 0.
