Hello Roy,

I am working on one of intermittent DHCP issue found in our device, and I would like to get your advices for "removing default route" issue observed on our device. Default route is actually removed by dhcp client on our device for the problem scenario and device cannot access network after that.

We are using DHCP client version 6.11.2, below is an error dhcp client logs from our device. Last message from the log indicates  "Oct 3 12:21:07 dhcpcd[409]: eth0: removing default route via 10.138.217.1".

Have you seen this type of error before? If yes,  what could be possible causes for this issue?
