Shulou(Shulou.com)06/01 Report--

The network topology diagram of a well-known enterprise and operator is as follows:

Enterprise projects should be as follows:

Experimental requirements:

1. As shown in the figure, the blue area is the intranet and the red area is the supplier network.

two。 Run MSTP protocol to balance the load of VLAN traffic

3.SW1 is the primary gateway for vlan 10 and 20, and backup gateway for SW1 30 and 40

4.SW2 is the primary gateway for vlan 30 and 40, and backup gateway for SW2 10 and 20

5.DHCP server is on vlan 66 and gateway is on SW2.

6. The intranet runs static routing protocol or OSPF routing protocol

7. All PCs automatically obtain ip addresses and can ping each other with Server1

8.Client1 can only access Server1's www service

9. Enterprise intranet devices are only allowed to be managed remotely by the IT department.

Step 5: verify.

Verify that PC automatically obtains the ip address and can ping the server1 server:

Verify that Client1 can access Server1's www service, but cannot ping the server

So far, the project has been configured and verified successfully.
