Yes, but some times ago Laine Stump says that for host side link
status we can use source element with link state.

OSPF - tap device have addresses assigned to it and bird/quagga create
routing based on interface link status and addresses on device.
So if i have host side device in up state no matter that have guest -
host system forward traffic to it. So i need to modify host side link
status too.
