The paper "Advanced Routing" is a wonderful example of an assignment on logic and programming. In this network task assignment, several factors will be considered where two different protocols exist in two different network segments and especially when there is an interest to upgrade the network system from the current IPv4 to IPv6. Just like most of the other systems some of these factors include the availability of the new system, the mode of addressing to be used types of connectivity, routing strategy, quality of service, scalability, and performance, reliability, accessibility, security, fault tolerance and some other minor factor making up the bigger network. Introduction In the computer networking environment, there is a transition from the older IPv4 to the latest IPv6 versions.
For it to be deployed, the current arrangement is mostly preferred to be left just as it is together with its protocols and hence a new protocol, which is compatible with the existing system, is therefore installed into the system. Since it is preferred to maintain the structure of the existing system, the Dual-Stack Model is used to serve in the implementation of the network structure.
The Dual-Stack involves the configuration of specific sections of the network. These include the VLAN, routing, or HA in the network topology. Since most of these configurations such as the VLANs and the physical inter still are configured in the IPv4 version, therefore, the VLAN configurations are also the same. Therefore, this type of configuration happens normally in the same layers of the two networks combined. Network Routing This is the network topology of the two networks when joined and already upgraded to IPv6. The routing strategies for his model embraced are the EIGRP for the cause of IPv4 as it is the case with the OSPFv3.
This OSPFv2 is o protocol that helps in authentication privileges. When dealing with the routing Access configurations, the implementation of the two networks to be merged is first assessed for compatibility with the model. This routed access design has an access layer that performs routing where the former design is one of its layers- the access layer being a component of layer 2 and that the premier layer 3 component is found in the distribution layer.
This is attractively designed according to the network designer because of its failover performance which has been improved. However, taking to account the fact that the spanning tree is not much needed, accounting for its popularity is necessary. This extension of the DSM to be a routed access design was an easy task. The move to select the DSN model in the transition of the network from IPv4 to IPv6 is a result of careful consideration that was made by having security, optimal performance, and high availability at the top priority in the network design.
The primary advantage of this routing model is that it does not need any tunneling within its borders. This method has got two protocols running which are called ‘ ships-in-the-night’ which means, IPv4 and IPv6 work alongside one another. Except that these two protocols share the same data point, there is no other dependency on one another as protocols. These two network versions; IPv4 and IPv6 have independent routing strategies. They exhibit a high level of availability and QoS, also together with security and multicast policies.
Being an EIGRP, this is the property that enables it to work comfortably with the other protocols.
