Task one: a comprehensive program and logic diagram
1, project goals
XX province supplies company's enterprise network has developed into a more business bearing platform, not only to continue to carry the office automation of the enterprise, simple data services such as Web browsing, bearing involved in enterprise production and operation of various business application system data, the data traffic will increase greatly, especially to the core network data exchange ability put forward unprecedented demands,
Headquarters of the network coverage of the construction of the project node and 14 cities, mainly in the provincial headquarters as the core, local node to access layer, city nodes use double line composition to headquarters as the core of double star network structure,
After the completion of the project, the network will carry business systems, office systems, network management system, etc, make the network data more secure, reliable, real-time transmission, to make sure the network is reliable, stable and economic operation,
2, the network architecture
The project adopts the network architecture for
Core node need to ensure that in the event of a single point of failure, the entire network can smooth transition, in the process of switching operations don't interrupt, adopts the core node
The project adopts the way of wan
Each branch USES the
At the core of the corporate headquarters switches two
3, equipment selection of the equipment at the beginning of measurement (simulated)
In the core node using router equipment selection
Each branch router selection
At the core of the corporate headquarters switch selection
4, protocol selection
Wan protocol selection
Routing protocol 1 choose
Routing protocol 2 choose
5, analog measurement topology graph (IP address)
Task 2: enterprise network deployment and configuration
1, the project application scenario
The enterprise network including management center, technical department, production department a few areas, such as a router R_Internet simulation network, equipped with public address, the business enterprise inside all the host of using private address, through used on export router address translation technology and access to the public,
2, the logic diagram
In 3 router and switch 2 to simulate a real environment, deployment and configuration of an enterprise data network, realizes the entire network connectivity,
3, the configuration requirements
(1) planning and configuration of IP address
Require companies to network users using 192.168.0.0/20 address section, in which each subnet addresses requirements are as follows:
Management center: 50 hosts
Technology: 100 hosts
Production: 150 hosts
Realize IP address planning, in the case of meet the demand of the entire network, each part using a different network segments, all gateway to use the last available IP addresses that the segment, and to all the requirements of the network equipment can carry out remote management, to use the management VLAN100 switches,
According to the above requirements, has made the following table is shown in the IP address planning, please mark each device on the network topology graph port and IP address and mask digits on each VLAN,
Subnet an IP address planning reference (N said student id)
Device name (host name) port IP address subnet mask
RA S0/2/0 192.168. N. 1 255.255.255.252

SW1 management Vlan 100 192.168. N. 14 255.255.255.252
SW2 management Vlan 100 192.168. N. 18 255.255.255.252
(2) the switch configuration
1) the basic configuration of switches
Configure the host name, the Enable password, domain name is disabled, VTY;
According to the table below for the devices in a network topology configuration Enable password and VTY password,
Device name (host name) the Enable password VTY password
SW1 cisco 123
SW2 cisco 123
2) planning and configuration of VLAN
According to the requirements of enterprise network, by department VLAN divided into: a VLAN 10 for management center, VLAN technology, 20 VLAN 30 for production, complete the VLAN configuration and port assignments;
The table below for the VLAN configuration and port mapping table, and routing between vlans
VLAN id name note port mapping
SW1 VLAN10 GLZX management center: Fa0/1 ~ Fa0/10
VLAN20 JSB technology SW1:11 ~ Fa0 Fa0//20
VLAN30 SCB production SW2: Fa0/1 ~ Fa0/10
VLAN100 ADMIN SW management VLAN SW1, SW2 exchange Fa0/24 do Trunk interface, put on all VLAN
(3) the route planning and configuration
The enterprises to form a network request adopts OSPF to realize entire network connected
1) the basic configuration of a router
Configure the host name, the Enable password, domain name is disabled, VTY password;
According to the table below for the devices in a network topology configuration of the Enable password and VTY password,
Device name (host name) the Enable password VTY password
RA cisco 123
RB cisco 123
RC cisco 123
2) router link configuration
? RB, RC router to achieve single-arm routing
? The router serial links between using PPP encapsulation; The clock rate 128000,
3) routing protocol requirements
? Enterprise between routers using dynamic routing protocol OSPF; Will be released each segment to OSPF;
? RA is connected to the Inernet export router, need to configure the default static routing, the default routing and distributed to the other OSPF neighbors;
? In this enterprise, if does not need to form a neighbor interface to disable routing updates.
? To reach the company internal network all IP connectivity,
Note: RA interface connected to the Internet address 202.0.0.1 instead,
4) access control and security maintenance
At the appropriate Settings on a router ACL, satisfy the following requirements:
? Prohibit access between department and production department;
? Enterprise network all network devices (switches, routers) management center can be accessed and only
5) with Internet access requirements
According to the network topology map, the enterprise network management center, is only required to technology department, production department to get to the Internet, by PAT on RA router, other do not need to access the Internet is not a network segment transformation, public network address with 202.0.0.1 implementation,
