What is Routing?

Routing is the process of selecting a path for traffic in a network, or between or across multiple networks. Routing is performed by a router, which is a device that forwards data packets between computer networks. Routers use routing protocols to determine the best path for forwarding data packets.

How Does Routing Work?

Routing works by using routing tables that are populated with network information, which is used to determine the best path for data packets to take. When a data packet enters a router, the router uses the destination address in the packet to look up the best path in its routing table. The router then forwards the packet to the next router on the best path until the packet reaches its destination.

Routing Protocols

Routing protocols are used by routers to exchange information about the networks they are connected to. This information is used to populate routing tables with information about the network, such as the best paths to take for data packets. Common routing protocols include RIP, OSPF, EIGRP, and BGP.

Router Security

Routers should be secured to prevent malicious actors from gaining access to the network. This can be done through the use of firewalls, access control lists, and secure passwords. Additionally, routers should be updated with the latest security patches to protect against known vulnerabilities.
