3.1 INTRODUCTION

Routers have essentially the same Link Layer protocol requirements as other sorts of Internet systems. These requirements are given in chapter 3 of Requirements for Internet Gateways [INTRO:1]. A router MUST comply with its requirements and SHOULD comply with its recommendations. Since some of the material in that document has become somewhat dated, some additional requirements and explanations are included below.

DISCUSSION

It is expected that the Internet community will produce a Requirements for Internet Link Layer standard which will supersede both this chapter and the chapter entitled "INTERNET LAYER PROTOCOLS" in [INTRO:1].
