Require
1. Configure IP address (omitted)
2. All routers use OSPF to establish neighbor transfer routes, requiring loopback interfaces to communicate with each other. R2 and R4 declare network segments 20.0.0.0/24 and 192.168.1.0/24.
3. Configure VXLAN. The gateway of the PC is on R2. It is required that the PCs can communicate with each other and the PC can communicate with R4.
