Hi,

Please don't drop ML from the thread.
You have to go to the node where Your router is hosted and investigate there 
in the agent's logs. If ports are DOWN, I would start with checking in the L2 
agent logs (neutron-ovs-agent or linuxbridge-agent, idk what You are using 
exactly).
If there is no any errors there, You can also check neutron-server logs, why 
ports aren't set to be UP as well as checking neutron-l3-agent logs on the 
node where router is hosted.
