Description of problem:
OCP is installed with IPI method on RHEV. 
Upgrade was done from 4.6.18 to 4.6.22 using stable-4.6 channel.
After upgrade, we observed that nodeIPs are flapping to apiVIP for master nodes and IngressVIP for worker nodes in oc get nodes -o wide output.

In below output, 172.26.128.5 is apiVIP which is static IP not managed by DHCP.

From node os4p-s9ds8-master-0:
~~~
2: ens3    inet 172.26.128.54/23 brd 172.26.129.255 scope global dynamic noprefixroute ens3\       valid_lft 178117sec preferred_lft 178117sec

172.26.128.5 IP should not be reflected in oc get nodes -o wide output. When it shows in command output, OCP cluster is not working as expected and some CO will go to degraded state.

Sometimes it is observed that 172.26.128.5 apiVIP is taken for pod IPs as well which are static pods to the nodes even at the time oc get nodes is not having that apiVIP.

Version-Release number of selected component (if applicable):
OCP 4.6.22

How reproducible:


Steps to Reproduce:
1.
2.
3.

Actual results:
Node is flapping in between the api VIP, ingress VIP(static IP) to regular node's IP(DHCP managed IP).

Expected results:
oc get nodes -o wide should not show api VIP ingress VIP.

Additional info:
Note: OpenShiftSDN is being used in OCP cluster.
