問題文

A router sits on a network that carries no broadcast traffic, so neighbors have to be listed by hand and the device has to reach out to them on its own rhythm rather than relying on multicast. The operator therefore needs the setting that says how many seconds pass between those outgoing greetings. Meanwhile a link carries traffic between two other areas on behalf of a virtual link, and that area has to hold complete routing information. Which pair is called for?
