F5 pool

Currently we have 3 ISP setup as a pool in F5 NLB and configured as Least Connections (member) previously. We are going to terminate one of ISP. We were told we could simply disable the member in the pool and there would be no impact to users. All users would be accessing internet thru another 2 ISP that handled by F5.
I am not really familiar with F5 and would like to see if someone help on how this is really going to work.

Thanks in advance!

F5 load balancer in your case was connected with 3 internet links so the following is the sonicwall concept and ofcourse the same concept works on F5 i beleave... may be terms are different...

so the main functionalities while sharing internet are:

actually all load balancers are works like Failover = when one link failes other will take precidense, Spillover = when the specified percentage of bandwidth is reach the other internet requests are automatically move to other internet link i.e (ISP2)
RoundRobins = each request shares each link i.e 1st request ISP1, 2nd ISP2, 3rd ISP3 and Fourth ISP1

above all there is probing linke if the one link is down the another link will take presidense  

just log on to your F5 go to pool in pool and check connection load balancing method

all the best

Thanks Shaik for your prompt response! The load balancing method is  Least Connections (member) in F5.
With what you said, even though there are current active connections on the ISP internet link that I am going to disable, all those connections will automatically failover to another 2 ISP without any impact. Am I correct?
