I agree with Matt that GTM is the ideal solution here for the reasons he described.

 

 

However, you could potentially configure LTM A to have the virtual for www.website.com pointing to a pool with 2 members that are the virtual servers on LTM B and C respectively. Then the connections would be farmed out to B and C based on whatever lb algorithm is defined on that pool. LTM A doesn't "know" that those aren't physical hosts.

 

 

The downside is that you will have to SNAT on LTM A. Otherwise, when the packets are sent through to the real servers behind B and C, they will be sent in response directly back to the client, bypassing LTM A on the return, and the clients will drop them. So you will lose visibility to the original client source IP on the nodes, which may or may not be a big deal for you, depending on whether they are currently logged and/or used for Webtrends (or similar).
