Hello Alex BCT, thanks for your suggestions, but all the scenarios are there configured , but still we faced the issue
Hmm, interesting! Though I very much doubt you'd agree with me... ;)
What platform are you running on? Is it hardware or VM's? If you are running VM's on VMware, you can check the security settings; https://docs.vmware.com/en/VMware-vSphere/7.0/com.vmware.vsphere.networking.doc/GUID-891147DD-3E2E-45A1-9B50-7717C3443DD7.html -
Doing a failover especially with MAC masquerading enabled can cause trouble because VMware stops sending traffic to the vSwitch port as it thinks that someone is either hijacking the MAC address or jumping between MAC addresses. - Temporary disabling these security features can help you troubleshoot this.
If hardware devices, have a look at the physical interface configuration and the switch configuration to make sure those are fine.
If no luck, if you do a tcpdump on the B device, do you see traffic coming in at all? Any ARP requests? And when you ping the B device from the gateway, does the gateway get the MAC address from the B device / traffic group?
