Routers are the devices that router the data packets between the computer networks. They are the devices that manage the internet traffic. Their purpose is to route the data packets between two or more computer networks. In internet the data is transferred in the form of data packets. Each data packet has it’s own destination address. The router reads the data’s destination and forwards the data packet to the right destination.
The data packet reaches to every node or the every router that is in the place so that it can find the correct router to get used. Each router has a routing table to verify the address that is carried by each data packet and routes it to the perfect destination.
These routing tables are of two types. They are either manual or dynamic.
Manual routing table:
These routing tables are to be changed manually or simply known as they are manually configured. Not very common.
Dynamic routing table:
These routing tables are modified with each requests and updated frequently by contacting with other routers in the network and enables the fast transferring of the data packets from one network to the other.
Also there are many types of routers that are deployed in many different types. They are as listed below.
- Core Router
- Edge Router
- Branch Router
- Logical Router
The above are the most commonly used router types and they are explained as below.
Core routers are the routers that are used by the Internet service providers. They are the most powerful form of routers and they are at the center forwarding the data from one end to the fiber optics backbone. These routers are the core routers of big enterprises and they forward data packets much faster than any other traditional routers.
Edge routers are not as powerful as any core routers. They are used mostly at the verge end of the LAN network devices where are connected to the public network connection. These routers are the most used commercial routers and also know as subscriber edge routers.
Branch routers, as the name suggests they connect two different office locations of a same office to WAN. They act as an intermediate between two edge routers and connect them via branch routers.
Logical routers are the configured part of the hardware router. It copies the functionality of the hardware and enables you to replicate it’s functionalities. It helps you to mimic many router domains with in the same router.
Wireless routers are just as like the traditional routers but gives you the great mobility for notebook laptops and mobile devices. They allow you to access the public network or the internet within their accessible range without wire connection.
Here we gonna look at the edge routers that we are using in our home and small office. We can log in to the home or office router using their default gateway IP address.
Some of the default IP address gateways are:
Using the above IP address you can easily log in to the router device. The ip address and their default router login details are given below.
