Hi VB,

 

 

VLAN configuration isn't sync'ed between the units, so can't you configure a MAC masquerading address for both units without affecting the other unit?

 

 

I'd be concerned about running active-active for LTM and even more so with ASM. There is a possibility of losing redundancy using an active-active config if either unit is loaded over 50% and one unit fails. With ASM, there are quite a few host processes which use CPU0. Some of the processes (some nice'd and some not) regularly use 100% of CPU0. This makes it difficult to gauge when the units are at 50% capacity.
