It depends on a scenario, if a host pc has router1 set as it's default gateway but the network that host1 wants to get to is connected to another router router2 then depending on the config of the router a icmp redirect may be sent to use router2 as the gateway to that network. However if the scenario is that the host wants to talk to a host on a alternate subnet where both subnets are bound to the same ethernet interface on the router then assuming there is a route between the two subnets then ip will route as normal.
