Question 217 of 239 from exam 200-301: Implementing and Administering Cisco Solutions

Question

Router A learns the same route from two different neighbors; one of the neighbor routers is an OSPF neighbor, and the other is an EIGRP neighbor.

What is the administrative distance of the route that will be installed in the routing table?

Answers

Explanations

A. B. C. D.

B

The Administrative distance (AD) of EIGRP is 90 while the AD of OSPF is 110 so EIGRP route will be chosen to install into the routing table.

The administrative distance (AD) is a metric used by a router to choose the best path when there are multiple routes to the same destination. It is a numerical value assigned to each routing protocol and represents the trustworthiness of the source of the routing information.

In this scenario, Router A learns the same route from two different neighbors using different routing protocols, OSPF and EIGRP. OSPF has an AD of 110, and EIGRP has an AD of 90.

The lower the administrative distance value, the more trustworthy the routing information source is considered. Hence, the route learned from the EIGRP neighbor will have a lower administrative distance and will be installed in the routing table.

Therefore, the answer is B. 90.
