What is the route preference value of an OSPF route?

The route preference value for an OSPF (Open Shortest Path First) route is indeed 10. OSPF is a link-state routing protocol widely used in larger networks. The way OSPF determines the best route is based on its own metrics and preference values.

In the context of routing protocols, the preference values help a router decide which route to install in the routing table when multiple routes to the same destination are available. Each routing protocol has a default preference value that is used when comparing routes. For OSPF, the default preference value is set to 10, which allows OSPF routes to be prioritized appropriately compared to other routing protocols like RIP (Routing Information Protocol), which has a higher preference value and could be used in specific cases where OSPF is not the optimal route.

Understanding this fundamental aspect of routing protocols is crucial, especially in environments where multiple protocols may interact and compete for routing decisions.
