Day18/100 #100DaysOfNetworking Todays focus was on STP, how it prevents layer 2 loops How root bridges are elected and bridge ID composition & root port How PVST+ runs a separate instance of spanning tree for each vlan .@ireteeh @TemitopeSobulo @segoslavia @NetworkQueenX @OnijeC

Day17/100 #100DaysOfNetworking Conducted a hands-on lab in Cisco Packet Tracer to deepen my understanding of VLAN Trunking Protocol (VTP) and Dynamic Trunking Protocol (DTP). Explored VTP Server, Client, and Transparent modes,and also how transparent mode rests revision number.

Day16/100 #100DaysOfNetworking Today was a bit busy but I focused on diving into VTP Which plays a role in VLANs by synchronizing switches databases across each other Understood the type of modes, versions and revision number. @ireteeh @segoslavia @TemitopeSobulo @OnijeC

Day15/100 #100DaysOfNetworking I focused on understanding the use of DTP in switches and how they automatically determine the operational mode of a port The difference between dynamic auto and desirable and also why it’s essential to disable it on switches with nonegotiation.

Day14/100 #100DaysOfNetworking Still on understanding VLANs today was about implementing intervlan routing using SVIs on a layer3 switch SVIs are faster and more efficient than ROAS because switching and routing are done on the same hardware. @ireteeh @segoslavia @TemitopeSobulo

Day13/100 #100DaysOfNetworking Implemented interVLAN routing using Router on a stick Configured trunk links with consistent native VLAN setting Created subinterfaces,also assigned appropriate ip addresses.@ireteeh @NetworkQueenX @OnijeC @TemitopeSobulo @sisinerdtweets @segoslavia

Day 12/100 #100DaysOfNetworking Today was about understanding VLAN more by practicing legacy inter VLAN routing ; Created VLAN 10(IT) and VLAN 20(FINANCE) on the switch Assigned switch ports to the appropriate VLANs Connected each VLAN to a separate physical router interface

Day11/100 #100DaysOfNetworking I focused on understanding the fundamental concepts of VLANs including frame tagging, trunking, access ports and the role of native VLANs. Also the function of 802.1q tags @ireteeh @TemitopeSobulo @segoslavia @sisinerdtweets @OnijeC @cybersafehq

Day10/100 #100DaysOfNetworking Today I engaged in VLSM exercises, created subnets for varying segment sizes, including point to point links.Also I had a review on all I had covered in the past few days. @ireteeh @TemitopeSobulo @segoslavia @OnijeC @sisinerdtweets @Cyblackorg

Day9/100 #100DaysOfNetworking Today I practiced VLSM in Packet Tracer. I split the 192.168.1.0/24 network into smaller parts. I used /30 subnets to connect the two routers with just 2 usable IPs each perfect for point-to-point links. @ireteeh @TemitopeSobulo @segoslavia @OnijeC

Day8/100 #100DaysOfNetworking Today was about understanding how VLSM works, how it allows us to subnet an address block even more efficiently by creating subnets of varying sizes. Also I practiced a lot of FLSM questions where I got to understand the concepts better .

Day 7/100 #100DaysOfNetworking Today I focused on digging into subnetting. I practiced breaking networks into equal sizes using FLSM, figuring out broadcast and network addresses and the importance of subnetting. @ireteeh @segoslavia @TemitopeSobulo @OnijeC @sisinerdtweets

Day 6/100 #100DaysOfNetworking Today I revisited TCP/IP where sequences and acknowledgement numbers prevent receiver buffer overflow. I also explored proxy ARP, a technique in which a router responds to arp requests on behalf of hosts in different subnets using its own MAC add

Day 5/100 #100DaysOfNetworking Connected 4 PCs across 4 routers,Configured interfaces and static routes on each router.Tested connectivity by pinging PC0 to PC2. Routers enable communication between different networks. @ireteeh @TemitopeSobulo @sisinerdtweets @OnijeC @segoslavia

Day 3/100 #100DaysOfNetworking Built 3 IPv4 subnets using 1 router + 3 switches. Connected each LAN to the router, enabled interfaces, and verified connectivity. Ping across subnets succeeded (first reply lost to ARP). Switches dynamically learned MACs. @ireteeh @segoslavia

Day 2/100 #100DaysOfNetworking Today I used Packet Tracer to visualize how a PC discovers another device’s MAC address. Watching ARP and ICMP packets move through the switches in simulation mode helped me understand how Layer 2 and Layer 3 work together.

Day 1/100 #100DaysOfNetworking I manually assigned IP addresses and ran a ping. Then I used simulation mode to see how the packet travels through OSI layers: Layer 1 : cables carry the signal Layer 2 : switch forwards frames using MAC addresses Layer 3 : ping uses ip add

Day 3/100 – Cisco Packet Tracer Lab Today I worked on DHCP (Dynamic Host Configuration Protocol). DHCP auto-assigns IPs using the DORA process: Discover, Offer, Request, Acknowledge. 🔹 Built 2 networks: 1️⃣ DHCP on Router 2️⃣ DHCP on Multilayer Switch #100DaysOfNetworking #Cisco

Day 100 #100DaysOfNetworking 100 days ago, this felt impossible. I didn't chase a cert, i chased consistency, discipline & the link btw networking & SOC work. It wasn't smooth, but finishing means sharper skills & stronger habits & the opportunity to compile- @ireteeh @segoslavia

Day 99 #100DaysOfNetworking I've been thinkn abt what all this networking grind really means 4 a SOC analyst, & definitely it is not abt configs, but hw the fundamentals shld show up when i am staring at logs/captures & trying to make sense of the traffic😓 @ireteeh @segoslavia

How are your networking skills? #100DaysOfNetworking

Today i did a full admin config for 2 switches, setting hostnames, console pwds, Telnet & SSH access (w & w/o usernames), privileges mode security using both weak & hashed pwds. Also practiced interface documentation. Felt like a full setup job. #100DaysOfNetworking @ireteeh

Day 1 of Networking with ChatGPT: Learned about VLAN configuration and troubleshooting. Learned how to configure inter-VLAN routing and practiced in Cisco Packet Tracer. #100DaysOfNetworking #NetworkEngineerInProgress #ChatGPTForNetworking #CiscoLabs #CyberSecJourney

Day 12/100 #100DaysOfNetworking Today was about understanding VLAN more by practicing legacy inter VLAN routing ; Created VLAN 10(IT) and VLAN 20(FINANCE) on the switch Assigned switch ports to the appropriate VLANs Connected each VLAN to a separate physical router interface

Day 5 of 100 #100DaysofNetworking #SteadyBombing 📍 Read a documentation by @mondelo__ on VLAN Conf. and SVI Conf. On L3 Switch and I practiced it using a different practice lab and it was successful 📍 Troubleshooted a practice lab... #networking

Configured IP settings on two switches using VLAN 1 for mgt, assigned IPs & default gateways so they cld talk outside their own network. Didn't touch VLANs or trunking but messed arnd with some commands. I just made sure the switches were reachable. #100DaysOfNetworking @ireteeh

Today's lab helped locked down console, Telnet & enable mode access across all devices. I even hashed the enable password, set up local login with real username & password for Telnet. It was fun as everything felt more legit & less random. #100DaysOfNetworking @ireteeh

Day 17 of 100 #100DaysofNetworking #SteadyBombing 📍Learnt STP Protocol States and Timers (Blocking, Listening, Learning, Forwarding and Disable 📍STP BPDUs Fields and their Purposes 📍STP toolkit 📍Will be learning STP configuration shortly

Day 81 #100DaysOfNetworking (I'm back😎) Feeling more like myself again, thanks to loved ones & modern medicine, i finally began Ch.28 on securing wireless networks which i approached with clear purpose after days of slowed momentum. Learned that - @ireteeh @segoslavia #SOC #CCNA

Day 14 of 100 #100DaysofNetworking #SteadyBombing 📍Revisited previous labs to keeping solidifying my knowledge base.
