stop advertising virtual address when pool members down

Hi all,   I have 2 virtual servers running on the same IP with different ports (443 and 2000) and therefore sharing the same virtual address (lets say 10.1.1.1 for example). This setup is repeated...

I'[m not exactly sure how this works when you've got 2 sites with same IP-addresses. What you can do is install an advanced routing license on the BIGIP's and use a dynamic routing protocol like OSPF to advertise your virtual addresses. You can advertise the same addresses with different costs

 

Every virtual address is then advertised as a /32 for IPv4 or /128 for IPv6. When all VIP's sharing the same virtual addresses go down the virtual address is no longer advertised to OSPF

 

Hope this helps
