This paper is a recommendation for the IPv4 and the IPv6 schema used at the China location for the West Consulting graphic design and printing company.

The China location has got 30 users and it uses the following network 196.100.6.0/26.

From the above table we can see that we are using the network 196.100.6.0 and the subnet mask is 255.255.255.192.In order to arrive to the number of subnets, is 192 which is two bit on, therefore 22 – 2 = 2. Therefore the answer is 2 subnets i.e. 255.255.255.64 and 255.255.255.128. The network requires 30 users but we decided to use the 62 host instead of using the 196.100.6.0/27 which produces 30 hosts per subnet for future expansion.

In order for us to integrate the two sites using IPv6 we will use tunneling. According to Tetz E (2019) tunneling is “passing IPv6 data over an IPv4 network by placing the IPv6 packet into the data section of an IPv4 packet”.

The current IP routing protocol in operation is EIGRP. EIGRP stands for Enhanced Interior Gateway Routing Protocol. According to Hummel S (2010) EIGRP is a routing protocol that is only used in Cisco systems. Hummel S (2010) adds that EIGRP supports both the distance vector and link state routing protocols. Hummel S (2010) continues further by saying that EIGRP supports hop count of 255 and it converges faster than IGRP since it uses an algorithm known as Diffusing Update Algorithm (DUAL). Hummel S (2010) adds that dual update algorithm is run when a router notices that a route is unavailable and only then the routing table is updated. When changes occur, only the affected routers are updated. EIGRP supports the use of VLSM (Variable Length Subnet Masks).

We intend to use a routing protocol that lacks hop count so as to support future extension of the network and also is not Cisco proprietary incase other routers that are not Cisco vendor are added in future. The routing protocol that we intend to implement is the OSPF. OSPF stands for Open Shortest Path First. According to Hummel S (2010) OSPF is a “link state routing protocol whereby link state advertisements is sent to all connected neighbors of the same area to communicate route information”. Hummel S (2010) adds that “when OSPF enabled router starts, a hello packet is sent to all directly connected OSPF routers”. OSPF is used in large networks and it supports Cisco vendor routers and other routers. With OSPF, a network can be divided to smaller internetworks called areas.

According to Lammle T (2004), when it comes to network convergence, “OSPF router calculates the best/shortest path to every network within an area”. This calculation is done using an algorithm known as shortest path first (SPF)”. The SPF algorithm calculates the shortest path from source to destination.

Performance is maximized because every router has got the same information about the neighboring routers and network.
