In a HA environment allow the virtual IP to be advertised using BGP peering to a nearby router in the same way that anycast DNS is implemented.
components needed:
- minimal BGP daemon to peer with adjacent router(s)
- way to control whether the virtual IP is advrtised or not to the adjacent router
- configuration of a BGP peer on the adjacent router to accept the virtual IP and add a unicast IP address to its forwarding table
(the site would be responsible for this)
