CirrostratusHi,
Very nice article. I am a bit confused by differences in article pictures (as well as in video "Setting up HA Groups (part 2 of 2)").
On first picture there are three HA Groups named ha_group_deviceA_tg1, ha_group_deviceB_tg1, ha_group_deviceC_tg1 (configuration in video is as well using those names)
On second picture all HA Groups are named ha_group_deviceA_tg1
Is that correct?
Another question I have is related to video. In presented config there are three pools, HA Group on each device is using different pool.
What is logic behind it? Each pool contains members only available on given BIG-IP, like members of poolA are available only on BIG-IP A and so on?
Or members from all pools are available via all BIG-IPs but each pool is containing members pointing to different servers? It makes little sense if members in all pools are pointing to the same servers because then member Down will be reported in all pools - except of course if each BIG-IP has completely separate network path to the same servers - or I am wrong here?
