問題文
A router in a provider network holds links in two ordinary areas and one more link in the area whose identifier is zero. The design team must set down what the leg into that last area has to amount to before the router may count itself among the routers that join areas, and which advertisements the router weighs for destinations outside its own two ordinary areas for as long as it does not yet count as one of them. Which pair fills the design note?
