这种设计导致了IP地址的浪费的消除和允许发展计划就未来的使用（mirzahossein et al，2013）
萨默顿# config t
除此之外，它还需要在兰波特路由器是由类似的命令取代“萨默顿’与’ Langport ‘做配置EIGRP。
EIGRP (Enhanced Interior Gateway Routing Protocol) is a routing protocol which is based on its previous version i.e. IGRP. In the central Somerset, the configuration of EIGRP is done between the Somerton, Street, Compton Dundon and Langport routers where the Autonomous System Number (AS) which is used across every router.
The Address of the network and the Subnet Scheme which has been used for this kind of network is 22.214.171.124/24 and allows the use of 254 hosts each of which consists of 8 bits. In order to meet the infrastructure requirements the network IP may be required to be added to the subnet.
This kind of design led to the elimination of the wastage of the IP address and permitted the use of the development plans with respect to the future (Mirzahossein et al, 2013)
Configuration of EIGRP
The EIGRP can be configured at the basic level itself and the two step process is followed for the purpose of the configuration so as to make the Central Somerset fully operational.
The first command used for the configuration is the (config) # Router EIGRP 123 and the network address which is needed to be advertised is (Config-if) # Network 126.96.36.199.
In order to configure EIGRP on the Somerton router, the following commands are used:
Somerton # config t
Somerton (Config) # Router EIGRP 123
Somerton (Config-If) # Network 188.8.131.52
Somerton (Config-If) # Exit
Other than this, it is also required to configure the EIGRP on the Langport Router which is done by the similar commands by replacing the word ‘Somerton’ with the ‘Langport’.
The purpose of route maps is to enable a control over the input and output during the process of routing the information. In addition to this, it can be also used for modifying the conditions for routing by implementing certain conditions. Thus, route maps helps for the purpose of routing the information from one protocol to the other. Furthermore, it can also be used for controlling the method of routing of the information.
In this report the detailed explanation has been provided for the purpose of designing of Central Somerset network by using the OSPF and EIGRP within the networked environment. Thus, this report clearly explains the importance of function Somerset system. The process of routing the information has also been studied.
