In this lab scenario you will take on the role of a Network Architect for a Cisco Partner.
One of your clients – S.T.A.R Labs has asked for a proposal to redesign their remote office network as they are expanding.

As the Network Architect, it will be your role to design the new IP addressing scheme according to the criteria laid out in the design document. An excerpt from the IP Subnetting section is given below in order to design, implement and then verify the new scheme in this Packet Tracer Assessment lab.

General Design detail:
1. S.T.A.R Labs are in the process of expanding their Remote Office locations as part of an acquisition program. The Office design will include a Central hub router to the remote sites, a remote site router for connectivity via serial connections and a switch at for client connectivity.
2. The IP Addressing scheme to be used for the entire Central City Office IP addressing design is to be 192.168.49.0 /24.
3. This Packet Tracer Assessment will use the 192.168.49.0 to create all the subnets required for the remote office connections. IP subnet-zero is configured.

Remote Site LAN Networks

4. You must create a VLSM scheme so that each of the 6 remote sites in the Central City Office Site locations can have up to a maximum of 28 clients on each of the access layer switches
5. No new VLANs are to be created on each of the remote site LAN’s. Each remote site switch management interface IP address should be configured with the lowest IP from each address space assignment. Ensure each switch can communicate with other network devices.
6. Each Remote site router LAN interface should be configured with the highest IP address from each address space assignment.
7. The links on all access layer switch facing each site router and client PC’s must be configured as static access ports, DTP is to be disabled and all in use non-trunked ports should transition to forwarding immediately.

Client PCs:
8. Assign the next lowest available IP addresses from each network address allocation to the 2 clients on each access layer switch. The lower numbered PC (1,3,5,7,9,11) attached to each access layer switch should have the lower IP address of the PC’s
9. Ensure that each client has a correctly configured default-gateway. Each remote site router will provide this service.
10. All clients should be able to ping the Central Hub IP address of 172.16.1.100 and be able to ping all other PC’s in other satellite office locations.

Central City Hub to Remote Site Serial Connections.
11. Once the remote office networks have been designed, you should use the last of the remaining subnets to create a VLSM IP Addressing scheme for the Router to Router connections.
12. The serial connections should be configured to use industry standard multiprotocol encapsulation. No authentication is necessary at this early stage.
13. The IP addressing scheme used must minimise any address wastage for the WAN connections. The Hub site interface should be configured with the lowest IP address from each address space assignment. The remote site should be configured with the highest IP address.
14. Site_1 will use the first available subnet from the VLSM scheme; Site_2 will use the second; Site_3 the third through to Site_6 using the 6th VLSM subnet to complete the design.
15. Ensure all interfaces are enabled and connectivity between the remote site clients can be established and verified with the Central City head office IP address of 172.16.1.100
16. Routing has already been configured on the Central City Hub site. You must configure the routing protocol on each of the routers to all networks to be learned on each of the Hub and remote site office routers.
17. Ensure that routing protocol packets are not sent onto the LAN networks on the remote sites.

You will be able to Check Results for your score. The Packet Tracer assessment file will grade you and point you to check certain conditions have been met to score this lab on.
As this is an assessment lab, a copy of the completed .pkt file has been provided for configuration comparison.
Good luck!
