OSPF

Open Shortest Path First (OSPF) is a dynamic routing protocol. It uses a link state routing algorithm, thus, it performs functions such as detecting topology changes and link failures. It generally converges quickly and in a loop-free manner. OSPF is often used in corporate networks within a datacenter or building.

While OSPF is not generally used as a mesh protocol across a city, it has properties similar to other mesh protocols such as use of link state routing algorithms and auto-convergence.
