Active-Active between two datacenters

We are deploying two BIG-IP LTM 4000 appliances this Friday. One will be at a remote datacenter, the other at my home office datacenter. The DCs are connected via 1 Gbps fiber, and running OTV betwee...

WLB, thanks for your response. If anything I say doesn't make sense, then it's because I'm 1) brand new to F5/BIG-IP platform and 2) not very smart.

 

My original implementation thoughts are something like this:

 

HA and Virtual Server addresses will be in OTV subnets between the two DCs.

 

Configure SNAT pool for local addresses, with a self/floating IP in that subnet on both F5s.

 

This would (in my theory) allow the real server IP addresses to remain local, while allowing for failover in the event one F5 was unavailable. Traffic would traverse the fiber link twice per request which obviously isn't ideal, but it would allow for load balancing to continue.

 

When it comes time to deploy the other services, my plan was to create a second traffic group with the other LTM as the primary, etc.

 

Does that make sense?
