High level diagram consisting of basic network infrastructure

• Mention routers, switches, access points, servers and workstations

• Finding out the cost of network equipment along with the Model No. and count of devices

• Consider geographical locations while designing your network.

• Use OSPF as the routing protocol. There are 5 offices, implement the area concept of OSPF and configure every office in separate area for example:

Boston-Area 1, Mumbai- Area2, Beijing- Area3, London-Area 4 and New York-

Area5 and Backbone network as area 0.

• Set the router ID manually in each OSPF routers.

• Implement HSRP for Boston and Mumbai office. Change the Hello timer to 2s, hold timer to 6s.

• Implement VLAN's for each department. Set only the VLANs used in the Networks as the VLANs allowed on trunk.

• Change the Native VLAN on the Trunk to the one used for HR department.

• Implement Rapid STP and switch redundancy for London and New York office.

• Enable Port fast and BPDU guard on all the ports that are connected to the host machine.

• Implement Frame Relay to improve the data rate.

• Defend MAC flooding attack in the HQ locations

• Area Border Router (ABR) in Boston can access all other locations ABR but not reverse. A technical department from Boston alone has an access to ABR of Boston [Hint: build a hardware connection]
