[j-nsp] ISIS route leaking from Level2 to Level1

[Cydon Satyr]

Hi Krasimir,

I'm aware that would work. Also, if aggregate is redistributed to level 2
as well (not just level 1), the originating router will not install this
route into RIB - but I was sure this behavior would work if route is
distributed into level 1 only as well.
