問題文

A provider brings up a BGP peering with a router that belongs to another operator, and the engineer who builds it attaches no route map to that peering at all. The routes on both sides of it are already in the tables the router keeps. The upgrade sheet has to set down which way or ways the protocol's own default treatment of such a peering runs, and whether a product may put a switch in front of the operator that brings the older treatment back. Which pair does the upgrade sheet state?
