[openstack-dev] A question on static routes on Neutron router

Yes, the extra routes extension allows IP addresses from any of the
networks connected to the router.

I see in the code that send_redirects is set to 0 so it will not generate
ICMP redirect messages in the case you mentioned. I don't see anything
obviously preventing the forwarding to a next hop on the same subnet, but
you would have to try it out to be 100% sure.
