ARP By VIP?

I've noticed issues with Failing over, the ARP table does not refresh completely. I am pretty confident in stating it's an issue with a device between our HA Pair.

 

But to resolve this on the F5, the visibility I am seeing is that specific VIP's on the F5 are not being presented in the ARP Table. This presents a problems for just the specific VIPs. The resulting action is a "Page Cannot be Displayed" Message and the VIP looks like it is down. Troubleshooting on the F5, everything is green, responses and health checks are clear.

 

Now, I have Critical and Non Critical VIPs that reside on the same interface as these VIPs. Is there any way to force an ARP update for one Specific IP on the F5 without impacting the entire Interface?

Hi,

Take a look on MAC masquerade (https://support.f5.com/csp/article/K13502)

MAC Masquerade looks like the long term solution.

 

What about a quick remediation in between?

 

Thanks
