What is the administrative distance of an OSPF route?

The administrative distance of an OSPF (Open Shortest Path First) route is 110. Administrative distance is a value that network devices use to determine the trustworthiness of a route received from a routing protocol, with lower values being considered more reliable. Here’s the relevance of the numbers provided:

• 110 is the correct administrative distance for OSPF routes.
• 115 is typically associated with IS-IS (Intermediate System to Intermediate System) routes.
• 170 is the administrative distance for external EIGRP (Enhanced Interior Gateway Routing Protocol) routes.
• 90 is the administrative distance for internal EIGRP routes.

Therefore, the correct answer for an OSPF route is 110.
