4 BIG-IP in one cluster?
Hello guys,
We have two data centers, with L2 link between the DCs. Is it possible to create one cluster (2 BIG-IP LTM in primary DC + 2 BIG-IP LTM in standby DC)?
And in case one of the services/links go down in primary location, the VIP for that specific service will be up in standby DC?
Is it a good practice?
Thank you.
It is sort of a good practice, but to shift traffic to a backup data center you would also use F5 DNS.
You would have two clusters, one in each datacenter. And F5 DNS would distribute traffic across data centers.
Take a look at this video: BIG-IP DNS Load Balancing Introduction
Otherwise you would have plenty of (virtual) hardware sitting idle.
