CirrusAAM - global acceleration for web application - how does request get to data center big-ip?
hi there, i m following along the guide for global acceleration for an web application. how does the remote big-ip know to forward the request to the data center big-ip? Is it because they share th...
As long as all the routing is in place, the request is forwarded/routed via IP to the matching central big-ip's v/s to handle. You can add a default pool to the remote big-ip v/s as a backup. Thanks!

CirrusStraight from the guide:
About symmetric request and response headers
In a global network that includes a symmetric deployment of remote and central BIG-IP®
devices across a
WAN, the remote BIG-IP device receives a request and includes an X-Client-WA header, which
distinguishes the request to the central BIG-IP device, enabling the central BIG-IP device to process the
request, as necessary. When the central BIG-IP device receives a response for the origin web servers, it
includes an X-WA-Surrogate header in the response, which distinguishesthe response to the remote BIG-IP
device, which processesthe response as necessary and removesthe X-WA-Surrogate header before sending
the response to the client
If this is the case then I m not quite sure why we are configuring a default pool for the remote big-ip. I have to believe its in case the central(data center) big-ip goes down?
