What is the administrative distance of connected route?
An administrative distance is a number between 0 and 255, with the lower number being better. The AD of 0 indicates the most trusted route (the directly connected network). The AD of 255 means that the route will not be trusted.
What is the administrative distance of the protocol?
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 administrative distance for default route?
The range for administrative distance is 0–255. The default value is 120 for RIP routes and 110 for OSPF routes.
Which command is used to display the routing table of a router?
show ip route EXEC command
Use the show ip route EXEC command to display the current state of the routing table.
What is the administrative distance of static routing?
1
By default, static routes have an administrative distance of 1, making them preferable to routes learned from dynamic routing protocols.
Which one has the 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.
Which route has the lowest administrative distance?
The most believable route or the route with the lowest administrative distance is one that is directly connected to a router.
How do you find administrative distance?
You can display the administrative distance of all routes on your router by typing the show ip route command:
- In the case above, the router has only a single route in its routing table learned from a dynamic routing protocols – the EIGRP route.
- Metric.
- RIP has been configured on all routers.
What does administrative distance rank?
What does administrative distance rank? Explanation: Sources of routing information is the administrative distance rank. It is used by routers to select the best path when there are different routes to the same destination. It’s used only two different routing protocols are being used.
Which command displays RIP routing table?
The debug IP rip command
Which command displays RIP routing updates? Explanation: The debug IP rip command is used to show the Internet Protocol (IP) Routing Information Protocol (RIP) updates being sent and received on the router.
When do I need to use administrative distance command?
This command specifies that the administrative distance is assigned to the routes learned from a particular routing protocol. You need to use this procedure generally when you migrate the network from one routing protocol to another, and the latter has a higher administrative distance.
How does the administrative distance of a routing protocol work?
Each routing protocol has its own Administrative Distance (AD), which is a value representing the trustworthiness of the specific routing protocol. If a router learns a destination route from two or more routing protocols, it selects the route from the protocol having the smallest Administrative Distance.
How to show administrative distance on a router?
You can display the administrative distance of all routes on your router by typing the show ip route command: In the case above, the router has only a single route in its routing table learned from a dynamic routing protocols – the EIGRP route. The following table lists the administrative distance default values:
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.
