Absolutely, here's the continuation and completion of the explanation about routing and how routers work:

Routing and Routers:

• Routing involves the process of forwarding network traffic from one network to another based on destination addresses.
• Routers are network devices that facilitate routing by forwarding traffic to its intended destination.

Basic Routing Process:

1. A router receives a packet on one of its interfaces.
2. The router examines the destination IP address of the packet.
3. Using its routing table, the router determines the best path to forward the packet.
4. The router forwards the packet to the appropriate interface towards the destination.

Example of Basic Routing:

• Imagine a router connected to two networks: network A (192.168.1.0/24) and network B (10.0.0.0/24).

• The router has interfaces with IPs 192.168.1.1 (network A) and 10.0.0.254 (network B).

• A computer on network A (192.168.1.100) wants to send data to a computer with the IP address 10.0.0.10 (network B).

• The computer on network A knows that 10.0.0.10 is not on its local subnet, so it sends the packet to its gateway, which is the router.

• The router's interface on network A receives the packet as the destination MAC address matches its own.

• The router strips the data link layer encapsulation, revealing the IP datagram.

  

• The router inspects the IP datagram header, finding the destination IP of 10.0.0.10.

  

• It consults its routing table and sees that the network 10.0.0.0/24 (network B) is the correct destination for the IP.
