Extract of sample "User Access Verification and Security"

Introduction The international Travel Agency is an organization with HQ in London and two other remote sites in Paris andRome. The organization branches are connected together through three routers that enable communication. The HQ and each branch has a number of PCs which are assigned IP address. The address space utilized was 192.168.156.0/22. This address was sub-netted in order to accommodate all hosts on the network. During subnetting available IP address, Network ID and respective subnet masks were populated. Sub-netting, however, helped in utilization of IP addresses and avoid wastage. This was done based on the number of Hosts in a given network. OSPF was used as the dynamic routing protocol on the routers. OSPF best fits the scenario because it was assumed that not all routers are Cisco. OSPF has the capability for route redistribution, which is a translation service between routing protocols using Dijkstra algorithm. OSPF converges quickly and supports multiple equal cost routes to the same destination (Parkhurst 444). Verification and Testing Plan Task # 2: Configuring dynamic routing OSPF routing algorithm was used to enable communication to remote networks. OSPF enables fast convergence in large networks and a default static route was configured on the London HQ router. The reason behind using OSPF is that it can support variable length subnet masks (VLSM) and non-contiguous subnets and therefore can meet all the demands of the organization. Task # 3: Configuring static routing A basic static route was configured on the HQ and propagated to all other branches in order to enable communication across the networks of the organization. Verification The ping command is used to verify TCP/IP Network layer connectivity to the default gateway and remote networks in Paris, and Rome.
