Delay in routing table update while switching from Ethernet to WiFi and vice-versa

We are working on Xavier NX Dev Kit. It is connected with a USB 3.0 USB to ethernet converter. Both ethernet and WiFi are configured.

We have observed while switching from Ethernet to Wifi, routing table update is taking more than 7 minutes. While switching from WiFi to Ethernet, it is taking 45 seconds.

Why this delay is happening and how to reduces it?

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.

Is there any dmesg or syslog info that can show you why it took 7 min?

Also, what is the behavior you observed there? I mean how do you know it took 7 min/ 45 seconds?
