H3C Switch configuration cross-switch VLAN Communication

1. Networking requirements: 1. switchA and SwitchB use trunk for interconnection. Mutual access is allowed between PCs with the same VLAN. Mutual access is prohibited between PCs with different VLANs. PC1 and PC2 are located in different VLANs. You can set the IP address of VLAN Interface 10 of the SwitchB layer-3 Switch to 10.1.1.254/24, when the IP address of VLAN 20 is 255.1.1.254/24, mutual access between VLANs can be achieved.
