What is the administrative distance of a static route?
1
Static routes have a default administrative distance of 1. A router prefers a static route to a dynamic route because the router considers a route with a low number to be the shortest.
What is the administrative distance of OSPF?
110
The range for administrative distance is 0–255. The default value is 120 for RIP routes and 110 for OSPF routes.
What is the administrative distance of a static route with a next hop address?
The default administrative distance for static IP routes is 1, but can be configured to any value from 1 to 255. The fixed administrative distance values ensure that the routing switch always prefers static IP routes over routes from other sources to the same destination.
Which route has the lowest administrative distance?
In the event of two protocols reporting the same route, the routing protocol with the lowest administrative distance will win, and its version of the route will be inserted into the RIB….Administrative Distance.
| Route type | Administrative distance |
|---|---|
| Connected interface | 0 |
| Static route | 1 |
| EIGRP summary route | 5 |
| External BGP | 20 |
What is the administrative distance of OSPF Mcq?
Solution(By Examveda Team) The administrative distance (AD) is a very important parameter in a routing protocol. The lower the AD, the more trusted the route. If you have IGRP and OSPF running, by default IGRP routes would be placed in the routing table because IGRP has a lower AD of 100. OSPF has an AD of 110.
Which type of static route is configured with a greater administrative distance to provide a backup route?
floating static route
A floating static route is simply a static route configured with a greater administrative distance than the dynamic routing protocols running on the Firepower Threat Defense device. When the corresponding route discovered by a dynamic routing process fails, the static route is installed in the routing table.
What is the default route preference value for OSPF?
Product and Release Support
| How Route Is Learned | Default Preference | Statement to Modify Default Preference |
|---|---|---|
| OSPF AS external routes | 150 | OSPF external-preference |
| IS-IS Level 1 external route | 160 | IS-IS external-preference |
| IS-IS Level 2 external route | 165 | IS-IS external-preference |
| BGP | 170 | BGP preference, export, import |
Is OSPF area 0 required?
Because OSPF is link state the LSDB must be identical within an area. This is to ensure that the SPF calculation is consistent and to prevent routing loops. If running single area OSPF any area can be used, there is no requirement to have area 0.
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 administrative distance of Open Shortest Path First routing protocol?
By default, OSPF has a default administrative distance of 110 and RIP has a default administrative distance of 120.
What is default route in OSPF?
Configures OSPF to advertise the default route (0.0. 0.0/0) to its neighbors, regardless if it is present in the routing table or not. The no form of this command sets the OSPF administrative distance to the default of 110.
Which type of static route is configured with a greater administrative distance to provide a backup route learned from a dynamic routing protocol?
Floating static routes are backup routes that are placed into the routing table if a primary route is lost. A summary static route aggregates several routes into one, reducing the of the routing table. Standard static routes are manually entered routes into the routing table.
Which route is preferred OSPF or BGP?
While BGP excels with dynamic routing for large networks, OSPF offers more efficient path choice and convergence speed. Border Gateway Protocol, or BGP, and Open Shortest Path First, or OSPF, are two of the most popular, standards-based dynamic routing protocols used around the world.
Why OSPF route is preferred over BGP?
Scale: BGP is more flexible and scalable than OSPF and it is also used on a larger network. Preferred path: OSPF is used to determine the fastest route while BGP puts emphasis on determining the best path. Protocol: In OSPF, internet protocol is used. While in BGP, transmission control protocol is used.
How to distribute static route via OSPF in Cisco IOS router?
The command to distribute static route via OSPF in Cisco IOS Router is “ redistribute static subnets ” and the way we applied this in the example is: Now after the redistribution command is applied, R3 will have the knowledge of how to reach R1 and R4 loopback address, as shown in the updated routing table below:
What is the default administrative distance of OSPF and BGP?
The default administrative distance of OSPF is 110 while that of the eBGP is 20. With the command distance, we changed the AD value of BGP to 190. Prior to this command, the router R2 preferred the BGP routes over OSPF since they had the default AD values configured. After the AD value of the BGP changed, the OSPF routes takes the precedence.
How to discontinue OSPF?
If your long term plan is to discontinue using OSPF then configuring a simple static route (no AD specified) will replace the existing OSPF route with the static route and then discontinuing OSPF would be quite straight forward. 12-16-2020 12:41 PM 12-16-2020 12:41 PM
What is the default administrative distance of a rip route?
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.
