DYNAMIC ROUTE HEALTH INJECTION / WITHDRAWAL

Hi I have dynamic routing working with the LTM and an adjacent Cisco router. All works ok when good in that I see the host route advertised to the Cisco router via OSPF. Strangely, when I disable the VS, the route is still advertised. I have also tried disabling the pool. My config is as follows: VIRTUAL SERVER: Notify Status to Virtual Address - Checked VIRTUAL SERVER: State is currently disabled

 

VIRTUAL ADDRESS: State is enabled VIRTUAL ADDRESS: Auto delete is ticked VIRTUAL ADDRESS: Availability calculation is When all vs are available VIRTUAL ADDRESS: Route Advertisement is set to All

 

I have tried some other permutations but the route is never withdrawn. I have been waiting around 20 - 30 seconds in the understanding that the ZEBOS router polls the LTM every 10 seconds for VS health.

 

Does anyone know what I am missing here for the routes to be withdrawn?

 

Thanks

    Hi

     

    Have a look on Table 2 of this link which should hopefully point you in the right direction. If you disable the Virtual IP or cause monitoring to fail (e.g. associate a UDP monitor for a TCP service or change the receive string ) then hopefully your routing table should then update
