R1 has learned route 192.168.12.0/24 via IS-IS, OSPF, RIP, and Internal EIGRP. Under normal operating conditions, which routing protocol is installed in the routing table?

A. IS-IS

B. Internal EIGRP

C. RIP

D. OSPF








 

Suggested Answer: B

Community Answer: B

With the same route (prefix), the router will choose the routing protocol with lowest Administrative Distance (AD) to install into the routing table. The AD of Internal
EIGRP (90) is lowest so it would be chosen. The table below lists the ADs of popular routing protocols.

Note: The AD of IS-IS is 115. The ג€EIGRPג€ in the table above is ג€Internal EIGRPג€. The AD of ג€External EIGRPג€ is 170. An EIGRP external route is a route that was redistributed into EIGRP.
