Adding persistent routes to a virtual router #13347
Description
Hello
We're having trouble adding or changing routes on a Virtual Router in an Isolated Network. After rebooting the Virtual Router, all routes are lost and have to be updated manually.
Is there a way to save added or changed routes in the Virtual Router's startup configuration so they don't get lost?

How did you add that route? Did you configure it under VPC → Static Routes?

this is not available for Isolated networks

@jeanvetorello I access the Virtual Router via VNC and use ip r del / ip r add to change network routes. I'm not using a VPC. I have an isolated network.

@weizhouapache Hello, could you please help me answer this question?

you may need a script and a systemd service which run the script every time when the VR starts.
However, when you restart network with cleanup, the systemd service and script do not exist in the new VR.
so, to achieve it, you can refer to https://www.shapeblue.com/customise-system-vms-via-user-data/
please note, the userdata applies to all VRs, so the userdata should be smart enough, based on the boot args of the VR (check /var/cache/cloud/cmdline).
