Unfortunately our towers aren't quite tall enough to reach the cloud and require some kind of intermediate device ;)

Thanks Dan. I've been skimming the archives but I will look closer. I've seen the ASR920 before but they use too much power. I forgot to mention in my original posting to the list that we're designing solar-only sites going forward. Aren't they essentially the same hardware, anyway?

Fantastic, and good to hear from you again Aaron! Currently we're used to that sort of behaviour as our PPPoE LNS dumps /32 routes for each subscriber. But thanks for the heads up and mention of your usage!



Thanks gents
