FRRv8.5.2 VRRP feature is not behaving properly on RHEL9.2 but Ubuntu 22.04.2 works

Does anybody uses FRR with VRRP on RHEL?

I know the FRR VRRP needs 5.1 kernel and above so that is why I am using RHEL9 because it has the latest 5.24 kernel. I also tried a RHEL8 with a newly compiled 6.3.9 kernel but it is pretty much the same behavior below. I also tried RHEL8 with 5.4.249 kernel from the ELREPO.

FRRv8.5.2

ISSUE: Using RHEL9.2 kernel 5.24 as base os for FRR with VRRP feature does not show correct behavior.
First: The vrrp failover from backup to master takes anywhere from 10-20seconds. On Ubuntu the failover is sub-second.

Second: The "OSPF redistribute connected" advertises the interface subnet that is configured with VRRP even when it is on "VRRP backup" state. I don't think that is the correct behavior. On Ubuntu FRR it only advertise the "OSPF redistribute connected" when VRRP takes over as "VRRP Master".

Third: I am not getting the correct mac address for the VRRP vip. Ultimately, I think this is the reason why the VRRP convergence is taking a long time since the mac address change. As I ping through the VRRP vip and when I list the arp cache using "ip neighbor" the mac address is not what I defined using the nmcli command below. The "ip add" and "nmcli" shows the correct mac-address. Ubuntu FRR works just fine..

The parent eth2 mac (IP 192.168.22.27) and the the vrrp vip mac (IP 192.168.22.1) is the same.

I used Network Manager to configure interfaces. I used the same commands on both RHEL and Ubuntu
