Set the port to routing mode, configure the IP address, test the directly connected computer, OK.
The second port is configured similarly
[H3C]int GigabitEthernet1/0/2
[H3C-GigabitEthernet1/0/2]port link-mode route
[H3C-GigabitEthernet1/0/2]ip address 2.2.2.1 24
[H3C-GigabitEthernet1/0/2]ping 2.2.2.2

There is no need to configure routing protocols on the Layer 3 switch, routing is completed automatically. The test is normal.
