GTM - Topology load balancing failover when one pool is down
Hello All, I am looking for a solution to the problem that has been raised several times, but I do not find a confirmed solution. The situation I am in is described in the following post: GTM Topology across pools issue when one of the po... - DevCentral (f5.com) We have two topology records with the same source, but different destination pools, with different wights: SRC: Region X => DEST: Pool A, wieght 200 SRC: Region X => DEST: Pool B, Wieght 20 When Pool A is down the Topology load balancing for the Wide IP still selects Pool A which is down, and no IP is returned to the client. If the topology load balancing selection mechanism, is not going to take in the status of the destination pool and just stop on first match in its selection mechanism, then why have "Wieght" at all. I do no believe disabling "longest match" would help as this just affects the order the topology rules are searched, it woudl still stop with the first match. The often mentioned solution is to use a single pool with Global Availability load balancing, as mentioned in the post: GTM and Topology - DevCentral (f5.com). The problem I have is that Pool A and Pool B are pools with mulitple generic host servers. I cannot have a pool with all generic host in it as we want to memebers in each Pool are Active/Active and not Active/ Backup Many thanks, Michael
GTM Wideip and pool persistence
Hi there , please help me understand the gtm wideip and pool persistence, gtm wideip persistence — this tells a specific user how long you will stick with the same pool member for dns queries gtm pool TTL: this tells the specific user, how often you would need to query the gtm for dns resolution, for instance, if I connect to a wideip and gets a pool member as response, 10.10.10.10, assume that I have enabled wideip persistence as 3600 s, and pool ttl as 15 sec, I will likely to get 10.10.10.10 for 1 hr, but for every 15 seconds a dns requests sends to wideip to see if the member is still active, is this accurate understanding? please confirm

Help with GTM load balancing with Cisco ASA AnyConnect
I haven't been able to find any documentation for guidance in configuring F5 to be able to do GTM for Cisco ASA AnyConnect RA-VPN. I'm trying to use our F5s to load balance our Cisco ASAv based AnyConnect SSL RA-VPN connections between two data centers.
