I think your characterization is accurate, i.e., a TTL of 24 hours which implies a more frequent beacon rate, to avoid a signed route from expiring. >An alternative to beaconing is a push model instead of pull.

Every AS that does not rely on default routes is potentially "interested" in the freshness of every origin's route announcement. So I don't see how a registration approach to trigger pushes will help. Also, a motivation for pushing the route freshness info via updates is because this reduces the need for frequent access to the repository system. The downside is that it creates the need to "refresh" a route that might otherwise not need to be announced. Steve
