ARP/MAC Tables Not Updating on Core Switches After F5 LTM Failover (GARP Issue?)

Thank you for the "tmsh load sys config" - we are relatively new to F5 and this will save us quite a bit of time.

Regarding MAC masquerading. Since each F5 LTM had dual uplinks to each Nexus Switch in a SEPARATE VPC/Port-Channel. Po127 = F51 and Po128 = F52. If the Standby unit doesn't send packets utilizing the shared MAC and we are already having issues with GARPs, that means that shared MAC would only be learned on one Port-Channel interface. When failover occurs, you're saying the new Active will start sending packets including the shared MAC and the switch CAM tables should update to reflect the MAC now being on a new Port-Channel interfaces (thus no need for GARPs)? Just want to make sure I'm understanding this 100% correctly.

I'm also going to be opening a TAC case with Cisco this morning to discuss this GARP issue as well to see if there is anything that can be done on the Nexus side to resolve this (or if it is indeed a bug).

Thanks for your help. I'll respond with what I find out.
