Configuring High Availability in F5 Big-IP LTM 11.x Config Sync Failover Trafficgroup

[@sackman11]

You're english is better than a lot of native english speakers. Great video!

[@michaelndlovu356]

The greatest video I've watched so far with the best explanations and illustrations. Thank you sir

[@forjobid]

Nice video. The explanation is very clear. Kindly make more videos for other F5 products as well

[@SUNNY-gg1vd]

Great Video

[@BloodyMer]

very old video, but I have to say auto fallback feature is very usefull if the connectivity between both F5 (and traffic group) are in different locations, so you may be running on the standby because failover happened moving that traffic group to the other site, because of that the inter CPD communication and lag may increase a lot. With this, after the delay set (to avoid flapping) it will go back automatically to the primary one solving those things

Great HA video. Excellent explanation and live configuration. Thanks for uploading. No need to worry about your English.

[@Ahmadkustian]

Can both F5s have the same Floating IP Address? Why?

[@RajaSharma-sj1oy]

Thanks, its really helpful.

[@davisli]

It was a very good video guide! If I have two boxes (VE actually), must their self-IP and floating IP be the same?

[@AnupamDas1027]

Li Davis must be in same subnet

[@taspea2]

Also make sure that NTP is set up and connected to NTP servers by running "ntpq -np" from bash.

Hi I have few queries here regarding election of Active and Standby Unit in active and standby scenario. Could you please explain on what basis the unit is elected as Active. Second query I have regarding the monitoring if one of the link connected on Active unit fails, will it failover to standby unit and how. Thanks in advance

Summary Steps: -Both Devices Self IPs - inside, outside etc DNS NTP Create HA Vlan, self IP - dedicated ha vlan Go to device - config sync - mention HA vlan - for confi sync between devices Go to device - failover - mention HA vlan - port udp 1026 - for hello, device state etc Go to device - mirroring - mention HA vlan - port tcp 1029-1055 for live connection mirroring device A device - device trust - peer device discovery - add peer device adding peer device -after this both in sync and active (No pools, vs sync yet) create device groups -name -sync-failover - this is config sync with device failover -add both devices -network -manual with incremental sync config and test failover..
