Springfield Assignment Instructionfrom The Given Information You Are

Springfield assignment instruction from the given information you are required to make a functional network. In Springfield, we have a router and four switches connected in a daisy chain topology. The current output of show commands indicates the network is non-functional, and you must implement a solution to make it operational. Tasks include analyzing show command outputs to identify problems and then providing solutions, configuring VLANs (Server VLAN, Instructional VLAN, Administrative VLAN), setting VLAN access methods, configuring Switch 1 as the root bridge, establishing trunking on all switches, setting the default gateway, creating and configuring interface VLAN1, and securing device access with passwords and banners.

The Springfield network's current configuration reveals several issues that impede optimal functionality and stability. Primarily, the daisy chain topology combined with unoptimized spanning-tree configurations leads to network loops, blocking ports, and potential network outages. Addressing these problems involves a comprehensive approach that includes topology restructuring, VLAN segmentation, optimized spanning-tree protocol deployment, and security enhancements.

Firstly, analysis of the show commands suggests that certain ports are blocked due to spanning-tree protocol (STP) roles, preventing proper data flow across the network. To rectify this, configuring Switch 1 as the root bridge is essential because it ensures predictable traffic flow and minimizes spanning-tree recalculations. Additionally, enabling trunking on all inter-switch links—using IEEE 802.1Q encapsulation—ensures VLAN information is properly propagated across switches, which is vital for segregating traffic per VLAN and maintaining network flexibility.

Creating distinct VLANs for Server, Instructional, and Administrative purposes enhances security and traffic management. The VLAN IDs are assigned as follows: VLAN 10 for Server, VLAN 20 for Instructional, and VLAN 30 for Administrative activities. Configuring access methods involves assigning switch ports to their respective VLANs and setting them as access ports. For example, port Fa0/1 on each switch can be assigned to VLAN 10 for server devices, Port Fa0/2 to VLAN 20 for instructional devices, and Port Fa0/3 to VLAN 30 for administrative staff. Security best practices involve securing these access ports with port security features that limit MAC addresses, preventing unauthorized devices from connecting.

Configuring Switch 1 as the root bridge involves setting the bridge priority lower than other switches using the "spanning-tree vlan 1 priority" command. By lowering Switch 1’s priority, it becomes the preferred root bridge, thereby ensuring the network's topology is shaped favorably. Security against rogue BPDU (Bridge Protocol Data Units) is achieved by enabling BPDU Guard and root guard features, which protect the topology from malicious or misconfigured devices attempting to alter the spanning-tree design.

The default gateway, configured on each switch, as well as the interface VLAN1, must be set to facilitate management access. For example, setting the default gateway to 10.30.1.1 allows network administrators to log into switches remotely. The interface VLAN1 is created on each switch with an IP address in the management network range, such as 10.30.1.2/24, allowing centralized management. Enabling HTTPS and SSH provides secure remote management channels, replacing less secure protocols like Telnet.

Implementing these configurations ensures a functioning, secure, and manageable network. The use of spanning-tree protocol in rapid PVST mode ensures quick convergence, reducing downtime during topology changes. The restructured topology minimizes unnecessary port blocking, prevents loops, and enhances overall network performance. Documentation of these configurations, along with regular updates and monitoring, sustains network health and allows rapid troubleshooting when issues arise.
