Week 12

For week 12, we have learned about RIPv1 and RIPv2. It is said that internet is divided into autonomous system wherein routing is referred to Intradomain routing (inside an autonomous system) and Interdomain routing (between autonomous system). 3 popular routing protocols:

• Routing Information Protocol (RIP)
• Open Shortest Path First (OSPF)
• Border Gateway Protocol (BGP)

To fully understand distance vector routing, you just need to follow the following: initialization, sharing and updating. Common problem about distance vector routing is instability or two-node loop instability. But it has solution to solve the problem which is defining infinity, split horizon and split horizon and poison reverse. There's a lot of things that we have discussed but I can't compressed everything here. But one thing's for sure, we have learned a lot from it.

Week 10

For week 10, we had implementing basic addressing scheme, basic router configuration, routing table and its principles, packet fields and frame fields, path determination. We also had a brief session about Dynamic and Static Routing.  We tried setting passwords for each router, configuring interfaces, configuring a banner, saving changes on the router and verifying basic configuration and router operations.

Sir Justin also made us try doing an example of Static Routing through packet tracer. We also discussed the dynamic routing protocols summary wherein we had that diagram to understand it. Sir Justin discussed the best path and metric for the routers which is hop count and bandwidth. Based on what he said, the best path is bandwidth. Lastly, path determination. Sir Justin taught us on how to get the IP address that is free to use. Then just some meanings and the meeting has finally ended with of course, the exercise. We shouldn't forget that.

Week 5 & 6

For week 5, we have talked about Application Layer Services. We just took the topic for, I guess, 1 meeting. We kept on configuring servers for us to learn. And for us to do it, we had an exercise.

For week 6, we have learned about transport layer and packet sniffing using Wireshark. We encountered Open Systems Interconnection Model wherein we deepen our understanding about the different layer in networking. In transport layer, we have learned the different responsibilities, functions and protocols that are commonly used. For packet sniffing, we had an exercise wherein we capture results using wireshark and 3-way handshake connection. We sniffed the Asia Pacific College (APC) website and TipidPC website. Sniffing encrypted traffic is worst, I guess.
