Which device is responsible for routing?
Answer:A router is a networking device that forwards data packets between computer networks. Routers perform the traffic directing functions on the Internet. Data sent through the internet, such as a web page or email, is in the form of data packets.
Why we need routing in a network?
To determine the optimal route for data to travel, networks employ a system called routing. Network routing examines every possible path that data can take across a network and chooses the route that the data will take. Routing is important for networks to get data where it needs to go as quickly as possible.
How does network routing work?
The work these routers do is called routing. Each of the intermediate routers reads the destination IP address of each received packet. Based on this information, the router sends the packets in the appropriate direction. Each router has a routing table where information about neighboring routers (nodes) is stored.
How would you determine if your devices are able to communicate on your network?
If your network is connected to the internet, then you have an external IP address. If your network administrator ported out your device then you will be able to connect to it from anywhere you have an internet connection.
How are routers used to make routing decisions?
This section explains how routers use information in data packets to make forwarding decisions in a small to medium-sized business network. This topic explains the encapsulation and de-encapsulation process that routers use when switching packets between interfaces.
How is routing table maintained in computer network?
The IP Address of the 4 subnets are: Then, Routing table maintained by the internal router looks like: To find its right subnet (subnet ID), router performs the bitwise ANDing of destination IP Address mentioned on the data packet and all the subnet masks one by one.
How is R1 used to make routing decisions?
R1 de-encapsulates the Ethernet frame to examine the Layer 3 information. Because the destination IPv4 address of the packet does not match any of the directly connected networks of R1, R1 consults its routing table to route this packet.
How does a router work on a computer?
A Router is a networking device that forwards data packets between computer network. This device is usually connected to two or more different networks. When a data packet comes to a router port, the router reads address information in packet to determine out which port the packet will be sent.
