It is usually the simplest things you miss. I had a MTU mismatch on the Nexus side.  Fixed that and everything came up.

Subject: [FROG] OSPF with FRR and Nexus

I have a Nexus 9300 that I am trying to get connected to FRR using OSPF. I have several Mikrotiks and other routers connected but this is my first Nexus. I think the issue is with my config on the nexus side. Any one have any ideas on what I missed?
