Redundant LTM3600 pair on different subnets

Currently, I am using LTM 3600 in a redundant pair (active/standby mode) inside the company's network. No traffic is coming from outside. Both units are configured under the same subnet1.   ...

Please explain layer 2 spanned network ?

 

 

 

Both data centers would need to be on the same Layer 2 subnet, ie, both on 156.118.x.0. Making that happen is probably a lot more expensive than a couple of GTM's.

 

 

It's not just a problem with the network failover. It's also because you could not share the same virtual server (or any other shared address - SNAT, gateway IP, etc.) across anything but a Layer 2 subnet.
