Changing the interface name where the external IP is.

[fcoulloudon]

Hi,

We are running RKE2 across multiple clusters, using public IPs as external IPs. These IPs are configured on a bonded interface that combines two physical interfaces connected to the same router.

When we change the setup by removing the bond and assigning the same IP directly to a single interface, RKE2 stops functioning, despite the IP address remaining unchanged.

Do you have any insights into why removing the bond would cause RKE2 to become non-operational?

Thank you!

RKE2 itself should not care which interface that is bound to. The CNI may care though. "RKE2 stops working" isn't very specific though. What exactly breaks? Are you rebooting the node or at least running the killall scripts after removing the bond? I would expect that the CNI would need to reinitialize after changes to host networking that move IPs between interfaces.
