Description of problem:
On AWS, when testing BGP vrf-lite, as nmstate and vlan is not supported, it need manually send cli commands on nodes to ensalve interface to cudn vrf.
After created cudn 'vrfred', login one worker node, try to add interface ens7 to vrfred as below. it was found that the command 'ip link set ens7 master vrfred' didn't take effect at the first time. After a second try, it worked.
Checked 'ip route show vrf vrfred', the ens7's direct route was not seen. After delete and receate the interface ip address, the route was shown.

3. create cudn
4. try to ensalve one interface to the vrf which generated by the cudn.
Actual results:
the configuration take effect on the second try.
Expected results:
