| Exam 200-301 | Question id=5527 | Network Fundamentals |
A router is running several routing protocols, and as a result has learned three routes to the 192.168.5.0 network. Below are the details about the three learned routes:
Routing Protocol Cost
RIP 5
OSPF 25
EIGRP 2269571
Based on this information, which route will be placed in the routing table?
| A. |
the RIP route | |
| B. |
the OSPF route | |
| C. |
the EIGRP route | |
| D. |
all of the routes |
The EIGRP route will be placed in the routing table. When a router learns multiple routes to a network from different routing table population methods, which includes routes from routing protocols and static routes created by the administrator, it does so in two steps:
* It selects the route with the lowest administrative distance.
* If multiple routes exist with equal administrative distance (usually meaning they learned from the same routing protocol), it chooses from the routes by selecting the one with the lowest cost
Since EIGRP has the lowest default administrative distance (90), the EIGRP route will be chosen.
The RIP route will not be chosen because it has a default administrative distance of 120.
The OSPF route will not be chosen because it has a default administrative distance of 110.
