Link not coming up (big3d:timed out)

Hi Guys, We have a link controller device which controls and load-balance across 2 internet links.(those who don't know much about LC, LC is like a subcomponent of GTM). Recently we were trying to migrate to a new Public Range on one of our link, so I decided to build both(new and old) public ranges in parallel. I configured the new range on internet router and link controller(along with vlan, self IPs etc.). But when I am trying to add new link(IP address of internet router) and assigning bigip_link monitor to it, its refusing to come up. Error I am getting is "bigip_link from /Common/MELYGDCLC1.computershare.com.au : no reply from big3d: timed out". Existing links are fine and up, and there is full connectivity between internet router IP(Link) and link controller. Can someone please help me troubleshoot? GTM logs are below

well it says the link doesn't reply, have you checked that the monitor gets the result you think it should? how is the bigip_link monitor configured?

 

there are also some known issues with this message, which version are you running?

So this issue has now been resolved. Following was completed to add the link to Link controller

 

* Create the new vlan

 

* Create Self IPs

 

* Create a node on LTM module for the new Internet router

 

* Create the new link in GTM module and assign big_ip monitor

 

But after doing this even though the node in LTM module is up and there is fill connectivity between F5 and new Internet router, Link in GTM module wont come up. But as soon as I added the link IP address to out default pool(one that is being referred in default route), link in GTM module came up.

 

But thanks everyone for their help.
