The question of where DHCP is was just one of asking what device is being a router, e.g., an appliance or the PC over virtual USB-ethernet (and an address is assigned so the router is working and the Xavier is talking to the router).

Normally this should not be an issue, but it is possible that the metric may change depending on whether the USB-C virtual ethernet is plugged in or not (NetworkManager can do unexpected things as one route or another is detected as changing).

This would fail if either the type-C USB is not connected, or if the host PC the type-C cable talks to is not set up to forward. The bridge is just a route to the USB virtual ethernet.

Thus the eth0 is the first device for access outside of the 10.216.0.19/24 subnet, and is as expected. The gateways: default _gateway 0.0.0.0 UG 20100 0 0 eth0 The one with the lower metric is used first if it is available, and switches over to the higher metric if the lower metric goes down (there may be some timeout period before there is recognition of a failed route). You have two gateways (only used if you access an address outside of the 10.216.0.19/24). This means the port is up and that DHCP worked between the Jetson and the router. Ifconfig indicates there is a valid address, 10.216.0.19 (with a “/24” subnet mask). I don’t believe the Ethernet router is set up to work with only specific MAC addresses because it worked for an out of the box Jetson Nano without any extra configuration.
