    Hi werner_verheyle , 

    First you should take this TMOS Version v14.1.5.2 and open F5 Bug tracker web site and see all of it's Bugs , maybe you will find bug related to BGP or BFDs or Advertising routes. 

    Look at this : https://cdn.f5.com/product/bugtracker/ID1134057.html 
    I got it from Bug tracker , it's a bug related to V14.1.5.2. 

    > the other thing , you have to raise a case with F5 support , you may get hotfix to cover this issue.

thx , i'll open a case for this .  

Just a remaining question , from bug report https://cdn.f5.com/product/bugtracker/ID1134057.html i can see this is also applicable on the version we use now ( v13.1.1.5 ) . So asking myself why we never encountered this before . Seems to be present in all version & only engineering hotfix will help

Hi werner_verheyle , 
I see there are multiple bugs related to BGP and BFD Flapping. 

anyway , Beside opening Case with F5 to request Hotfix , 

Review this Article please : https://my.f5.com/manage/s/article/K15923612#proc1

navigate virtual address  settings to see if { Route advertisement } enabled or not , also have you checked it after upgrade or not ? 

I recommend that you can try to upgrade in VE as a test to V14.1.5.2 and see if the Route advertisement value in each Virtual address changed in Version 14 or everything still the same.
