If Existing VIPs are working well then try to delete wideip config n recreate once again. Hope ping n telnet is working well from GTM.

To clarify, your bigip VE is running both LTM and GTM, not separate VEs?

Hi.. using the predefined "http" monitor in both the gslb server objects and gslb pool.

If you remove the http monitor from the gslb server and pool do the virtual servers go green? The gslb server (your bigip) should have the bigip monitor assigned to it, that is enough for gtm to see that the virtual servers are available. Have you tried a different monitor? TCP for eaxmple?

when I remove the http monitor, the status turns to Blue/unknown both on the gslb servers and pool. Yes tried "gateway_icmp" but still red/offline. Wondering if the GTM is trying to get to the LTM to check the monitors but cant - iQuery maybe? How could I check iQuery communication on single VE instance - any ideas ?
trying to paste /config/bigip_gtm.conf contents but cant as being categorised as spam. Any suggestions what the correct method is please ?
Thanks

Use the preformatted code button above the comment field to insert the contents of bigip_gtm.conf. Each line of the code should be indented using tab then check the preview field it should look the same as it does in the conf file. Here's an example:
gtm datacenter /Common/Miami { } gtm server /Common/gtm_4 { addresses { 10.10.4.31 { device-name /Common/gtm_4 } } datacenter /Common/Miami monitor /Common/bigip virtual-server-discovery enabled virtual-servers { /Common/http_vs_ltm4 { destination 10.10.4.100:80 } /Common/listener_50 { destination 10.10.4.50:53 } } }

The servers webserver1_rd and webserver2_dy are these addresses of VS on the LTM? Do you have the bigip itself created as a gslb server object? If not create one using an external self-ip address, product type "bigip single", assign to datacenter, and assign the bigip monitor. The GTM itself should be the first gslb server created in the config since it is responsible for running the monitors.
