All that as less and less real routers[tm] have FE connection in them where you could work on link-state... and you need a 'dynamic' component to tell you the connection over some GE aqggregation gear is still there, and if you combine this with the monitoring of the service itself it should pretty much work out. Mind you, this is theory. Looks quite sound to me though.
Speaking of which, whatever happened to MARP?

This in combination with UDLD sounded good to me when I heard about it a couple of years ago.

On the subject of UDLD, does anyone know why no mechanism was included in 10GE for UDLD? In 1GE there is autoneg which fixes this, but it's gone in 10GE. I just cannot figure out why anyone would actually remove such an operationally important feature, and now try to implement it in software instead of on the link layer.
