問題文

A provider brings up a router that already reaches two peers in other autonomous systems and one peer of its own domain. The engineer has applied neither an import policy nor an export policy to those peerings yet. The design note has to set down how the router treats the routes that a peer offers over such a peering while the policy slot sits empty, and how far the same default rule reaches across the two kinds of peering. Which pair belongs in the design note?
