NimbostratusBIG IP Link failover happen but i try to link fallback
hi Prasad21l
Could you please share the configuration Flow.
For me I expect you have a Firewall Sandwich solution > we called it like that when BIGIP sits down between 2 firewalls but in this case you have two routers instead of Firewalls.
I will explain what I understood and let me know if I am correct:
1- you have wildcard Virtual server >> Traffic goes through it to internet.
2- you have pool with two members ( Wan1 & Wan2 )
3- you are configuring a transparent health monitor , to monitor bother of links.
So let me ask you here , do you use PGA "Priority Group Activation " on pool level or not ?
I need to know the Configuration criteria of choosing the active link and when it marks it disabled.
so let me know more about the context
NimbostratusHi Mohamed,
Thanks for the reply,
Flow f5-->switch-->FW-->SW-->DMZ
1- you have wildcard Virtual server >> Traffic goes through it to internet. ----- yes
2- you have pool with two members ( Wan1 & Wan2 ) ---- yes
3- you are configuring a transparent health monitor, to monitor bother of links. -- yes
No Priority Group Activation configured.
very well,
I recommend using Priority group activation , please follow this article : https://my.f5.com/manage/s/article/K13525153
this will let you leverage :
1- Fault tolerance on Pool members level ( WAN1 & WAN2 ) , for example this selects WAN 1 as the primary and active link whereas WAN2 is standby in case of failures in WAN1.
2- If an issue happened in WAN 1 "Active Link" , WAN 2 will carry over traffic , and when WAN 1 returns back , WAN1 will get the traffic again and WAN2 will be standby again automatically by default.
By the way you can change this behavior and return traffic to WAN 1 manually if you wish in the future.3- Using this approach will give you the visibility and granular control for traffic flow.
Try it and let me know.
