I think you do not have a l3 plugin configured in your neutron.conf -
therefore the l3 extension is not being loaded and the router resource does
not exist.
If the l3 plugin is not there just add it to service_plugins.

If the diagnosis is correct, can you post this question to ask.openstack.org
(if it's not already there).
This is probably a typical problem that many users face when they start
deploying neutron.
