  1. Mountain Sky TCS Network Proposal for Mountain Sky Elementary Created by Chris Widmer and Stacy Ochar

  2. TCS Outline • Objective / Requirements • Infrastructure • LAN / WAN network topology • Access Lists • Security • Cost • Advantages / Disadvantages • Implementation Time

  3. User Requirements • Minimum Anticipated Network Life Span: 7-10 years • Design Considerations: • 1000% LAN Growth • 100% WAN Growth • host minimum access at 1 Mbps • server minimum access at 100 Mbps • Networking Protocol: Entirely TCP/IP • Class B Network subnetted

  4. User Requirements Con't. • Security: • Access Lists - the School LANs’ only remote access is through the District Office • Internet access via Frame Relay • double firewall on public backbone • Central Office is the Network Administrative Center

  21. Access Lists - WAN District Office Access (network # 150.96.1.0) • access-list 101 permit tcp 150.96.0.0 0.0.255.255 any eq dns • access-list 101 permit tcp 150.96.0.0 0.0.255.255any eq smnp • access-list 101 permit tcp 150.96.0.0 0.0.255.255 any eq www • access-list 101 deny ip any any • int s0 • ip access-list 101 • access-list 20 permit 150.96.1.0 0.0.0.255 • int s0 • ip access-list 20 in

  22. Access Lists - LAN Teacher Network (network # 150.96.12.0) Static Address • access-list 3 permit 150.96.1.0 0.0.0.255 • access-list 3 permit 150.96.11.0 0.0.0.255 • int e0 • ip access-list 3 in

  23. Access Lists - LAN Student Network (network # 150.96.13.0) Dynamic Host Configuration Protocol (DHCP) • access-list 2 permit 150.96.1.0 0.0.0.255 • access-list 2 permit 150.96.12.0 0.0.0.255 • int e1 • ip access-list 2 in

  24. Access Lists - LAN Administrative Network (network # 150.96.11.0) Static Address • access-list 1 permit 150.96.1.0 0.0.0.255 • access-list 1 permit 150.96.12.0 0.0.0.255 • int e2 • ip access-list 1 in

  25. Access Lists - LAN Enterprise Server (Host # 150.96.16.2) • access-list 5 permit 150.96.1.0 0.0.0.255 • access-list 5 permit 150.96.11.0 0.0.0.255 • access-list 5 permit 150.96.12.0 0.0.0.255 • access-list 5 permit 150.96.13.0 0.0.0.255 • int e3 • ip access-list 5 in

  26. IP Protocol Addressing Mountain Sky Elementary Router • Serial 0 port (to District Office) ip unnumbered to save on subnet addresses • Serial 1 port (to Service Provider) ip unnumbered to save on subnet addresses • Ethernet 0 port ip 150.96.12.1 • Teacher Network Switch ip 150.96.12.2 • Teacher Workstations assigned static ip address within network 150.96.12.0

  27. IP Protocol Addressing Mountain Sky Elementary Router Con’t. • Ethernet 1 port ip 150.96.13.1 • Student Network Switch ip 150.96.13.2 • Student Workstations assigned DHCP ip address within network 150.96.13.0 • Ethernet 2 port ip 150.96.11.1 • Administration Network Switch ip 150.96.11.2 • Administration Workstations assigned static ip address within network 150.96.11.0 • Ethernet 3 port ip 150.96.16.1 • Enterprise Server ip 150.96.13.2

  28.
