- b)IGRP has a lower administrative distance.
- c)RIP has a higher metric value for that route.
- d)The IGRP route has fewer hops.
Correct answer is option 'B'. Can you explain this answer?

RIP has an administrative distance (AD) of 120, while IGRP has an administrative distance of 100, so the router will discard any route with a higher AD than 100.

Explanation:
The reason the RIP route to this network is not used in the routing table is because IGRP has a lower administrative distance compared to RIP. Administrative distance is a measure used by routers to determine the trustworthiness of routing information received from different routing protocols.
Administrative Distance:
Administrative distance is a numerical value assigned to each routing protocol. When a router receives routing updates from multiple protocols, it uses the administrative distance to determine which route to choose. The route with the lowest administrative distance is considered the most reliable and is used in the routing table.
Comparison between RIP and IGRP:
- RIP (Routing Information Protocol): RIP has an administrative distance of 120.
- IGRP (Interior Gateway Routing Protocol): IGRP has an administrative distance of 100.
Impact of Administrative Distance:
In this scenario, since the IGRP route has a lower administrative distance of 100 compared to the RIP route with an administrative distance of 120, the IGRP route is considered more reliable. Therefore, the IGRP route is chosen and used in the routing table, while the RIP route is ignored.
Other Factors:
The other options mentioned in the question are not the reasons for the selection of the IGRP route over the RIP route:
- Option A: The update timer does not impact the selection of the route. It only determines how frequently the routing updates are exchanged between routers running the same routing protocol.
- Option C: The metric value is specific to each routing protocol and does not affect the administrative distance. Even if the RIP metric is higher, it does not matter because the administrative distance of RIP is higher than IGRP.
- Option D: The number of hops is not considered in this scenario. Administrative distance takes precedence over the number of hops.
Therefore, the correct reason for the selection of the IGRP route over the RIP route in the routing table is that IGRP has a lower administrative distance.
