Part Number: AM5716
Other Parts Discussed in Thread: AM5718, DRA722, TCA9535, PMP, ADS7950
1)The am5716 has 5 network cards, and 3 network cards have been enabled. I set a virtual IP address for all three enabled network cards, but only the eth4 network device encountered communication problems.
2)When I connected to the Ethernet network through eth4, I found that I could not access the Internet. When I grabbed the network packet, I found that it was connected to the Internet through a socket bound to a virtual IP address. In fact, it should be connected to the Internet through a socket bound to the main network card of eth4. The other two network cards do not have this problem.
3)The first red box in the figure below shows the IP addresses of the primary network card and virtual network card of eth4. The second red box shows the route command results of the system.

The following figure is a screenshot of the captured network packet. It can be seen that the socket is bound to the virtual IP address of eth4:
