During the period of time while the hold-down timer is active the route metric is set to 16 inside the routing table.
But is the route advertised as such, with metric of 16, during the hold-time timer period? I would find this weird, as it would propagate false information to the neighbours.
Or the route is advertised with the original metric received by the router from its neighbour ?
Or the route is not advertised at all?
