F5 DDOS (version 17.1.1.1 ) adding self MAC address for Destination for outbound traffic.

Hi all,

I am Kuldeep Singh.

I am facing an issue with the F5 BIG-IP DDoS device, which is operating in transparent mode. The DDoS device is adding its own MAC address for the destination IP for outbound traffic.

I have checked all configurations, including interface settings, VLAN settings, VLAN groups, and route domains, and everything seems to be fine.

Upon reviewing the DDoS device logs, I found that the DDoS device is adding its own MAC address for the destination IP, causing the traffic to fail.

I also checked the dynamic ARP table on the DDoS device and found that it is not receiving the MAC ARP from the next hop (LLB).

The traffic flow for outbound traffic is: Firewall → LLB → DDoS → Router.

This issue has been ongoing for 20 days. I kindly request your assistance in resolving this issue.

let me know if any other information require.
