           According to the above figure, the problem I currently encounter is that SW3 cannot restart the VLAN, try no shutdown, and the up status is not displayed. The feedback from Ping gateway is as follows:
%Unrecognized host or address, or protocol not running.

Experimental requirements:
1. SW1 SW2 2F SW3 3F
2. PC configures DHCP to obtain fixed IP and PC3. PC4 cannot be pinged, but PC4 can pingpc3, and everything else can be pinged
3. R1 single arm R2 R3 SW3 GW OSPF process 10 area 0 VLAN can be connected.
4. GW configures DHCP to assign to PC, NAT accesses the Internet in VLAN 10 and 30, and VLAN 20 and 40 cannot access the Internet
5. Telnet server maps port 23 to 100.1.1.1:10000 of the Internet. Remote telnet server can be accessed through the command telnet 100.1.1:10000 on the Internet

Note: please see the picture for the detailed configuration. The ISP is not equipped for the time being. Connect the intranet first.
Personal thought: I think the addresses are automatically obtained from DHCP and are announced in using OSPF protocol (not announced except for the Internet), but they are unsuccessful.
