LTM and GTM device Interface

Hi, I have an LTM and GTM device , where both have the same management IP. If i add that particular in LTM device as GTM server in the GTM server module and also i had enabled the bigip monitor. The Server of GTM showing that available but the Virtual Servers are not getting autodetected or even if i add the virtual server it is not coming alive. Is there any other option to bring it to live ???
