問題文

A customer site hangs off two provider routers over one bundle, and both of them pass traffic at the same time. A broadcast frame that comes in through one of them must be kept from returning to the same site by the other. The filtering rests on a tag that names the segment a frame arrived on. An operations note has to say where that tag has to live in the tables of the far router, and which of the two ends settles the tag's value. Which pair does the filtering note give?
