Below is made up of two routers connected three Ethernet to the Internet, which subnet 1 and 2 is the user host network, a subnet is 3 server network, now assume that the host in subnet 1 H1 browser to access the Web server in subnet 3 H2 (domain name at www.hzdx.edu.cn), please write in H1 browser displayed on the www.hzdx.edu.cn home page of the communication process in detail,

R1 and R2 interface address according to the above configuration has been completed,
R1 on 1 to 8 0 to 128.30.33.129 complete subnet subnet 2 routing
R2 on 8 0 to 3 128.30.33.130 complete subnet to subnet 2 routing such two subnets can communication,
Then in the subnet 3 DNS servers will www.hzdx.edu.cn 36.10 and web server address in the DNS server for DNS
Write 128.30.36.12 H1 of the DNS server and then on the R1 can normal visit

R2 on 8 0 to 3 128.30.33.130 complete subnet to subnet 2 routing such two subnets can communication,

This is why ah, can you explain??????

Because you all network under r2 are going out to a subnet 2, you can put the subnet 2 as the public Internet is not up to the net, I understand the difference between picture and the reality is you and 1 also constitutes the subnet line on both sides should be able to reach you can ping each other host test validation

CodePudding user response:

Thank you thank you! See here, the 8 0 there is how to understand

CodePudding user response:

8 0 is 0.0.0.0 0.0.0.0 represents all segments all hosts, such as 192.168.1.0 0.0.0.255 this limits the network segment can only be 192.168.1.0 network segment of the host can reach the next jump, write 8 0 means all segment can be reached
