GTM/LTM functioning as a LinkController

Hi,     I read somewhere that if you had the GTM and LTM modules installed on the same unit then you could achieve the same functionality as a link-controller (if not more).     ...

When you create the WideIP you will associate the virtual servers with it, so LC will know which link to use because it knows which network range is assigned to which link.

 

 

You need some sort of health monitor on the links, I typically use either a transparent ping to some known hop outside the border router (maybe even several that hit Google, Yahoo, etc and require at least one to be up) or SNMP to the router. If the health monitor fails, the link will be marked down and the associated virtuals will no longer be handed out for the WideIP.
