When ip routing is enabled, the router will look into its route table to
determine which interface should the packet be sent out. If there is no
route for the destination, the packet will be dropped.
When ip routing is disabled, with either an default gateway configured or
not configured. If the router has a default gateway configured, all packet
will be sent to the gateway, so the router will only send arp request for
the gateway's MAC. However, if the router doesn't have a default gateway,
the router will assume all destination is directly connected, so it will
send ARP request for any destination.
I am not sure if I have explained it clearly will my poor English. :(
Please let me know if you have any questions.
