HCIP - static routing experiment

1. Experimental requirements

1. R6 is an ISP, and the interface IP addresses are all public addresses, and no further configuration can be performed on them;
2. R1-R5 are LANs, with private IP addresses 192.168.1.0/24, please allocate them reasonably.
3. Therefore, the route is looped back , both represent the interface connecting the user;
4. The two PCs under R3 automatically obtain IP addresses through DHCP 5.
The optimal routing table for route selection should be as small as possible to avoid loops
;
.R6telnetR5's public IP address, actually log in to R1.
8. R4 and R5 normally pass through the 1000 link, and pass through the 100M link in case of failure;
