Additional info:
[OCPBUGS-53198] VRF failed getting local/host addresses for net1
https://github.com/containernetworking/plugins/pull/1151
Error is most likely due to the kernel taking too long to add the addresses. However, I saw that local link IPV6 addresses, as well as, connected routes are reinserted after slaving the interface to the VRF. This is not correct. Above PR, fixes this. Internal tests will be run with this fix to see if issue is solved. If not, the waiting time will be increased from 100 ms to 1 s in a new commit.
Upstream VRF test case also failed
