Nothing new or particularly exciting. *sigh* Anything else?

By the way, does Juniper have an analog of ip verify reverse-path unicast?
As well, I vaguely recall somebody in cisco-nsp mentioning cisco's
extensions to rpf unicast verification, something like "ip verify
reverse-path unicast relaxed", when it would drop packets that are not in
FIB at all rather than in FIB for this particular interface packet is
received on. Does Juniper have something like this or have plans to have it
implemented? (I could not find anything about these extensions on cisco web
site, though..)

Thanks,
