TDA4VM: Two default route configurations cause DNS resolution to fail

Part Number: TDA4VM

Hi  experts.

I do the following routing configuration in the system(two default routes)

Unable to ping domain name,but you can ping the IP of the domain name。

The phenomenon is as follows:

Specify the network port to ping the domain name: ping -I eth0.16 www.baidu.com

The packet capture found that the vlan port in the DNS protocol does not correspond to the source ip address.

The actual ip and vlanid correspond as follows

If it is ping IP (ICMP protocol) will not have this problem.

Is there a DNS protocol problem caused by the TDA4 platform? Or is there some configuration missing from the system?
