What is distance in networking?
1. For any two locations in a spatial network, their network distance is the length of the shortest path between these two locations along the network. The shortest path is computed based on the travel weight, such as travel distance or travel time, of network edges.
What is the difference between a directly connected network and a remote network?
The routing table of a router stores information about the following: Directly connected routes—These routes come from the active router interfaces. Remote routes—These are remote networks connected to other routers.
How can I connect to my home network remotely?
When you’re away from home, you can just point a browser to myhome.homefpt.net:8080 to access your router’s Web interface and manage your home network remotely. This works with almost all home routers, except for those from Apple.
What is the total distance to a destination through a specific neighbor router is known as?
Reported Distance(RD) – Reported Distance, or RD, as advertised by a particular neighbor, is its current total distance to a particular destination. It is simply the neighbor’s own distance to the destination.
How does a distance vector routing protocol work?
A distance-vector routing protocol in data networks determines the best route for data packets based on distance. Distance-vector routing protocols measure the distance by the number of routers a packet has to pass, one router counts as one hop.
How do you calculate distance vector routing?
Router A receives distance vectors from its neighbors B and D….At Router A-
- Cost of reaching destination B from router A = min { 2+0 , 1+3 } = 2 via B.
- Cost of reaching destination C from router A = min { 2+3 , 1+10 } = 5 via B.
- Cost of reaching destination D from router A = min { 2+3 , 1+0 } = 1 via D.
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 a directly connected network?
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.
Can I connect to my router remotely?
To connect to your personal router remotely, go to your web browser on your phone. Type in your router’s IP address. It’s the same IP address you used when you were setting up the remote access. After that, you can now access all your router’s features from your phone.
What is advertised distance?
The Advertised Distance (AD) is the distance from a given neighbor to the destination router. This requirement states that in order for a route to be feasible the Advertised Distance of the alternate route must be lower than that of the Feasible distance of the current route (see example below).
What is the administrative distance of a route?
The administrative distance is the first critera that a router uses to determine which route to use if two protocols provide route information for the same destination. Because the directly connected routes have the lowest possible administrative distance value, they will always be placed in the routing table.
What is the feasible distance of a route?
The feasible distance is the metric of a route from a neighboring router’s perspective. d. The feasible distance is the EIGRP metric associated with each possible route to reach a subnet. Answer: B. The Feasible Distance (FD) is, for all known routes to reach a subnet, the metric for the best of those routes.
Which table has the best path to a remote network?
Answer: E. Successor routes are going to be in the routing table since they are the best path to a remote network. However, the topology table has a link to each and every network, so the best answer is topology table and routing table.
What is a directly connected network?
Directly connected networks are added to the router’s routing table if the interface connected to the network has an IP address configured and is in the up and up state. Connected routes always take precedence over static or dynamically discovered routes because they have the administrative distance value of 0 (the lowest possible value).
