Question
Subnetting: Properly subnet addressing blocks to accommodate the site's VLAN sizes. You will not need to implement VLANs here; rather, you will create the correct sizing to properly accommodate the devices stated per the xACME educational topology. Carefully consider the challenges faced when structuring subnets too large and/or too small during your design. The starting Worchester site addressing range is 10.20.0.0 /16 (per the xACME educational topology diagram). Formatting per subnet should follow the format below and should be clearly stated and placed within a table.

Remote locations vary in terms of size and requirements. Some implementations will require current site router/switch-running configurations, which will be provided. All sites will use the following four VLANs, but you will need to configure only what is asked per site (some assumptions will be made).
Existing VLANs, per xACME:Faculty VLAN
used by faculty on-site for all office locations (non-instructional communications)
total devices per site will vary
Administrative VLAN
used by staff on-site for business administrative communications
total devices per site will vary
Academic VLAN
used by faculty and students for classroom labs and instructional communications
total devices per site will vary
Server VLAN
used by IT staff for all technology/management communications
total devices per site will vary
The types of devices per site will be the same; however, the number of deployed devices may vary (all documented in the xAcme educational topology).
Routers Per Site:
Switches Per Site:
Note: Device type will not impact your configuration commands and implementation of ALL required technologies will use Cisco IOS commands/concepts learned in our TestOut lecture(s). Standard switchports will be configured and used as trunk OR access ports, and DCE ends should be noted when configuring serial ports per router.

Explanation / Answer
protect the devices from bogus BPDUs.Note: When approaching the spanning tree challenge, do not concern yourself with the multipleVLANs at this time. Focus simply on the default VLAN1, which is the active VLAN that all portsbelong to in this topology at this time.Please refer to the following configurations:o SpringfieldSw1o SpringfieldSw2o SpringfieldSw3o SpringfieldSw4Worchester SiteRequired Implementation: Subnet addressing to accommodate Worchester siteSubnetting: Properly subnet addressing blocks to accommodate the site's VLAN sizes.

Summarizationaddresses should be stated per router in Boston’s topology. Consider redundancy upgrades as
well and document per topology.Routing Protocol: Research the different routing protocol types (distance vector/linkstate/hybrid) and choose a routing protocol implement (OSPF, EIGRP, RIP). Justify yourselection by defining its strengths and weaknesses. Define the proper addressing block toassign per point-to-point links and implement your solution per all three routers. Routingprotocol should be set up in a way to advertise all IP subnets, WAN, and LAN interfaceson a router. Be sure to protect the advertisements of the routing tables as well.Summarization: Define the route summarization addresses for each Boston site router.These addresses will not be implemented on the routers, but they will be documented inyour response. Each summarization address must be large enough to include all requiredsubnets contained within the underlying site subnets.Default Route: Any traffic not matching internal networks will need to be routedoutward. Implement default routes on the site routers to exit this traffic.Topology: Consider the potential challenges with the current Boston site topology(cabling and redundancy approach). If improvements are needed, update the topology anddiscuss and routing redundancy approaches you see fit.Please refer to the following configurations:o BostonSiteRouter1o BostonSiteRouter2o BostonSiteRouter3Sacramento Site VLAN, Routing on a Stick (ROS) and DHCP Implementation(Focus on the Sacramento Site Only)Required Implementation: VLANs, ROS, and DHCP implementationVLANs: Implement the VLAN database on the Sacramento site switches. Explain theassignment of switchport modes and how to implement each. Demonstrate how toimplement port security on the switchports to allow only two MAC addresses per portand shutdowns for violations. Additionally, consider proper security management of anyunused ports.o Provide the VLAN IDs, ports with matching switchport modes, and sampleconfiguration of port security and port management steps.
ROS: The site will be treated as a routing on a stick (ROS) topology. Provide a sampleconfiguration for Sacramento fa0/0 interface to support the multiple VLANs and interVLANrouting.o To simplify configuration, please use the following addressing:faculty VLAN: 10.50.0.0 /26administrative VLAN: 10.50.0.64 /26instructional VLAN: 10.50.0.128 /26server VLAN: 10.50.0.192 /26DHCP: The site will need a solution to manage the deployment of IP addresses. Brieflyexplain the purpose of DHCP and provide implementation of the DHCP configuration forthe VLANs. Be sure to include the pool name, exclude the last 10 addresses of eachsubnet range and configure the gateway, subnet mask, and DNS address (Sacramentofa0/0 address).Please refer to the following configurations:o SacramentoSw1o SacramentoSw2o SacramentoSw3o SacramentoRouterLos Angeles Site Management Technologies (Focus on the Los Angeles SiteOnly)Required Implementation: Device configuration remote storage, remote management ofswitches, ACL implementation, and an NTP solution.Remote IOS Storage: The site will require remote storage of the devices' configurations.Server details are provided per your topology. You will determine the protocol to use anddemonstrate how to implement the solution.
