With OSPF you can't filter prefixes, since it's a link-state routing
protocol.  At least most implementations I've dealt with does not allow it.

With RIPv2 you can, though, so I guess you can with RIPng as well.  FWIW
I've used RIP to connect customers that doesn't want the complexity of
BGP, where I generally just send them a default route, and import
whatever they send me into OSPF - if it passes my RIP filters, that is.
