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.

Yes it’s neutron router. Well the router is centralized. It is located between the subnets and the node, all the subnets will pass through the router to internet, but I don’t know what else check to set it up for. I’m using a friend’s Openstack instance on a server to check out if I’m missing something and both nodes are the same. I will send you a screenshot of my network Topology.

When I see the router_external it says all the interfaces are DOWN.

By router_external, You mean neutron router, right? If so, what kind of router it is, centralized HA or non-HA, or maybe DVR? Is router scheduled properly to some node? You can check that with command like "neutron l3-agent-list-hosting-router <router_id>".

I have search in everywhere but I can't find a solution for this.

Thank you for your time
