[c-nsp] RIB-failure - anything to worry about?

So basically, you are proposing to propagate the /18s and the /20s via iBGP
rather than with OSPF? Fine for me, it that removes this scary 'r', it's a
good idea.

... but I am already out of that danger, right? If my IX router looses
connectivity to the core, it will loose the route via OSPF, and will stop
announcing it via eBGP, correct?
