Priority group activation - what if lowest priority group has less servers than the "less than" setting?

Hi,

First scenario :

• Activation: less than 3 servers
• PG 2: 4 servers*
• PG 1: 2 servers

Based on this official article "If the number of available members in the highest priority group drops below the minimum number, the BIG-IP system also distributes traffic to the next higher priority group"

So 2 servers in PG2 goes down, traffic will be load balanced between the 2 remaining servers in PG 2 and both servers in PG 1.

You can also look at the following video from min 10 to the end it demonstrates this scenario.

Second scenario :

• Activation: less than 3 servers
• PG10 = 4 servers (2 down 2 UP)
• PG5 = 2 servers (2 UP)
• PG1 = 1 server (UP)

When 2 servers fails in PG10, the less than 3 servers active in the highet priority group (PG10) is matched, the load balancer will look to the next highest priority group to have at least 3 servers active. At this point, PG10 has 2 servers UP and PG5 has 2 UP (a total of 4 servers are UP) then PG1 will not receive any traffic. If we loose all PG10 servers then PG5 and PG1 will receive traffic.
