1. Design Description lans to connect to the ISP through a serial network and to Il and middle enterprise then access to the Internet. The company's plan is as follows: use the private addresses. The range is from 192.168.1.0/24 (1) Internal IP addresses 4. Internal omputers access to external networks based on NAT.(It is only required to make a configuration without verification) of the management, the company network is requested (2) In order to meet the needs LAN20, VLAN30, VLAN40. to divide into five VLANs. They are VLANI, VLANIO, v (3) The company's internal computers use a public network address, 202.199,100.101/30, as the IP address for the company to access the external network. 12 (4) The network management works in VLANI. The network uses a class CADDE (5) The server works in VLANI0. The network uses a class C ADDF (6) There are 360 computers in the development network. They are working in VLAN20 (7) The office network has 50 computers. They are working in VLAN30. (8) There are 10 computers in the production network. They are working in VLAN40. (9) The data can be transferred between every VLAN Please design the network according to the above requirements. 2. Reference topology (1) The PC1 and PC4 belong to VLAN20; (2) The PC2 and PC5 belong to VLAN30; (3) The PC3 and PC6 belong to VLAN40; (4) The PC7 belong to network management's network. It is working in VLAN1 (5) The ServerI belong to server's network. It is working in VLAN10; (6) AR2 is used to external netwo simulate the external network. The interface is S4/00. IP address is 202.199.100.102/30 1. Design Description lans to connect to the ISP through a serial network and to Il and middle enterprise then access to the Internet.
