The primary goal of this activity is to develop foundational skills in designing IP addressing schemes, configuring devices, implementing static and dynamic routing protocols, and verifying network connectivity using Cisco Packet Tracer. The exercise simulates a multi-region network with distinct subnetting requirements, demonstrating best practices in configuring Cisco routers and ensuring network resilience through proper routing strategies.

Firstly, the activity requires designing an IP addressing scheme tailored to specific network requirements. The key constraint is that the routing protocol in use is RIPv1, which is classful, thereby precluding VLSM or CIDR. This necessitates subnetting two large Class B address spaces (10.1.0.0/16 and 172.20.0.0/16) into subnets capable of supporting the largest host requirements in each region: 1,000 hosts in Region 1 and 500 hosts in Region 2. To accommodate these, the subnet masks must be selected carefully, avoiding VLSM, and ensuring consistent subnetting across the network.

Secondly, the task involves documenting the subnetting scheme, assigning specific subnet addresses to routers' interfaces, and configuring IP addresses accordingly. The addressing scheme must follow the guidelines specified, such as assigning subnet 0 to the LAN connected to FastEthernet 0/0 on B1-R1 and sequentially assigning subnets to subsequent LANs and WAN links in both regions. Proper documentation ensures clarity and facilitates troubleshooting, and the assignment of addresses begins with the first IP and subnet mask for each interface, particularly focusing on the WAN links where routers connect to each other and to ISP routers.

Following successful addressing, the activity proceeds to device configuration, where each router in the topology is configured with basic settings including interface IP addresses, passwords ('cisco' for login, 'class' for privileged secret), and clock rate for serial interfaces. The ISP routers are configured as DCE devices for WAN links. Static routes are then configured on each ISP router to ensure connectivity between the two regions, with emphasis on using local interface addresses to make routing decisions effective.

Once static routing is implemented, regional routers are configured to use RIP version 1. RIP routing enables dynamic update of routing tables within each region. Special considerations include disabling RIP updates on unnecessary interfaces to prevent unnecessary traffic and configuring default routes where needed to ensure routers have a default gateway for unknown destinations. Redistribution of default routes into RIP further enhances routing efficiency and convergence.

Finally, the network's functionality is validated by testing connectivity using ping commands from each router to all other routers’ interfaces and web servers. Troubleshooting is essential if any pings fail, involving verifying IP configurations, routing tables, and interface status. The goal is to achieve full end-to-end connectivity, confirming that the network operates reliably and as designed.
