What is the correct administrative distance for a route learned through OSPF?
110
It shows that the RIP routes are preferred. They are learned with an administrative distance of 90, although the default is 120….Default Distance Value Table.
| Route Source | Default Distance Values |
|---|---|
| IGRP | 100 |
| OSPF | 110 |
| Intermediate System-to-Intermediate System (IS-IS) | 115 |
| Routing Information Protocol (RIP) | 120 |
What is the administrative distance of OSPF Mcq?
Solution(By Examveda Team) OSPF has an AD of 110. RIPv1 and RIPv2 both have an AD of 120, and EIGRP is the lowest, at 90.
What is the lowest administrative distance?
A directly connected will always have the lowest, at 0. A static route will always have an AD of 1, EIGRP is 90, and OSPF is 110.
What is the administrative distance of OSPF quizlet?
OSPF has an administrative distance of 110.
What is the correct order of the operation of OSPF?
What is the correct order of the operations of OSPF? Explanation: OSPF first implements a hello protocol. Then it later on tries to establish synchronisation with database. Later on building of routing tables is done.
How do I change administrative distance in OSPF?
To set an administrative distance:
- For RIP and OSPF, issue the distance command in Router Configuration mode. host1(config-router)#distance 100. The range for administrative distance is 0–255.
- For IS-IS, issue the distance ip command in Router Configuration mode. host1(config-router)#distance 80 ip.
What metric is used for OSPF?
Open Shortest Path First (OSPF) uses “Cost” as the value of metric and uses a Reference Bandwidth of 100 Mbps for cost calculation.
Which one has a highest administrative distance?
Administrative Distance (AD) is a numeric value which can range from 0 to 255. A smaller Administrative Distance (AD) is more trusted by a router, therefore the best Administrative Distance (AD) being 0 and the worst, 255.
What is the default administrative distance of Igrp routes?
1.0 is an IGRP route. Ruth has chosen the IGRP route because, compared to RIP, IGRP has a lower administrative distance….Administrative Distances.
| Table 11.1. Cisco default administrative distances. | |
|---|---|
| Route Source | Administrative Distance |
| EIGRP | 90 |
| IGRP | 100 |
| OSPF | 110 |
Which is better OSPF or EIGRP for administrative distance?
The lower the better…as you can see EIGRP has a lower administrative distance (90) than OSPF (110) so we will use EIGRP in my example. Keep in mind: The administrative distance is only local and can be different for each router. The administrative distance can be modified.
What should the administrative distance be for Rip routes?
In order to enable the router to prefer RIP routes to IGRP, configure the distance command on R1 like this: Now look at the routing table. The routing table shows that the router prefers the RIP routes. The router learns RIP routes with an administrative distance of 90, although the default is 120.
When to change the administrative distance of a route?
There are no general guidelines to assign administrative distances because each network has varied requirements. You must determine a reasonable matrix of administrative distances for the network as a whole. One common reason to change the administrative distance of a route is when you use Static Routes to backup and existing IGP route.
What is the administrative distance for R2 router?
The routing table shows that the router prefers the RIP routes. The router learns RIP routes with an administrative distance of 90, although the default is 120. Note that the new administrative distance value is relevant only to the routing process of a single router (in this case R1). R2 still has IGRP routes in the routing table.
