Your other sites have no IP address info so there is not much to go on there. OSPF is a dynamic routing protocol. It is very, very useful as what is called an IGP, interior gateway protocol.

This article dives in deeper into how to setup the Raspberry Pi as a dual-protocol router using OSPF. The commands that you will need to execute to install the needed routing packages are as follows.

Three typical types of routing protocol are chosen as the simulation samples: RIP, OSPF and EIGRP. RIP (Routing Information Protocol) is one of the oldest routing protocols still in service.

A complex routing protocol that shares information with other routers in order to determine the best path. IS-IS was the first comprehensive link state protocol, and OSPF and NLSP evolved from it.

At Layer 3, routers will use dynamic routing protocols (generally Open Shortest Path First or OSPF and BGP in most enterprises) to present a robust network that handles site-to-site link failures and ...

One way is by using dynamic routing protocols, such as the Routing Information Protocol (RIP) or Open Shortest Path First (OSPF), which automatically create and update a database, or routing table.

The issue affects the implementation of the Open Shortest Path First (OSPF) routing protocol and its Link State Advertisement (LSA) database in particular. This protocol is used for determining ...

One of my complaints about dynamic routing protocols is they could be much better/simpler. But OSPF in particular was developed with many limitations in mind (compute, RAM, making up for RIPs sins).
