As a result of a known issue BIG-IP with BGP configured may continue to announce routes even after disabling the virtual address or disabling route announcement on the virtual address.
Prefixes continue to exist in the BGP table even after disabling the virtual address (visible via imish with the "show ip bgp" command); which will continue to announce the prefix to configured peers.
BGP configured with multiple routes announced via Virtual-address route announcements. Configuration changes made on the BGP configuration itself. Virtual address or its route health announcement disabled.
Workaround would be to restart the dynamic routing process.
BGP may no longer keeps announcing routes after disabling route health injection
