Question
If Router 1 and Router 2 are mis-configured so that packets from 192.168.1.X/24 destined for 192.168.2.Y/24 and vice-versa just bounce back-and-forth between Router 1 and Router 2, what happens to a packet sent from Host 1 to Host 2? Is an error generated? What happens to the error? What would you expect to see happening at Host 1? At Host 2?
What would the default gateway be for Host 1? Host 2?

Is an error generated? What happens to the error? What would you expect to see happening at Host 1? At Host 2? What would the default gateway be for Host 1? Host 2?Explanation / Answer
If a least cost path exists in the routing table of router 1 to send the packet from host1 to host2 then of course the packet bounces back and forth betwen Router 1 and Router 2 thus leading to a time out error occcurs and update to the routing table that the cost of the path is infinity. thus the router tries to find an alternative path and finds a path as:from Switch 1 to Router 1 to Router 3 to Router 2 to Switch 2 and then to destination.
Thus at Host 1 a distination not reachable(timed out) error will be seen. But if the routing table gets updated as explained above, subsequent packets can be delivered.
The default gateway for Host 1 is 192.168.1.245/24
The default gateway for Host 2 is 192.168.2.245/24
