BIG-IP Mac Masquerade

Jason Rahm details the BIG-IP Mac Masquerade feature, which is used in high availability configurations to allow for smooth transitions of traffic during failover from active to standby systems by maintaining the same mac address.

Hi, thank you for the video. Which BIG-IP product would you use to load balance your LAN traffic? Sorry, trying to understand which BIG-IP product does mac masquerading?

[@devcentral]

Hi Kashif, all the BIG-IP products, hardware or virtual, are capable of doing HA. Cloud environments might need different/additional failure mechanisms.

Does mac masquerade help in preventing asymmetric routing, so imagine I have f5’s in HA and their gateway is configured on a Firewall. One leg of f5 is in dmz and other goes to management like a 2 arm mode and default route points to management.
By configuring Mac masquerade, does f5 cache the source mac from where the client came and skip route table look ups. ARP look ups for return traffic and just forward the path that came in ?

[@devcentral]

mac masquerade is just there to help with layer 2 issues during a failover, it should not impact your routing strategy.

Hello. How to choose base mac address? Is it recomended to use 00:01:7d prefix?

Okay...Don't do this flipping the video stuff to make your writing go the right way. It's distracting and trippy...Looks unnatural as all hell.
