본문내용

Chapter 1. Routing Principle
1. Classful Routing Protocols Overview
 Classful Routing Review
 Classful환경에서 패킷을 받는 Router는 모든 advertise되는 subnet과 관련된 Routing mask를 알아야만 함
 receiving 라우터는 advertising라우터와 같은 subnet을 공유
 mask가 서로 틀린 경우 default subnet mask를 사용함
 Example : RIPv1, IGRP (Cisco Only)
 Classful Subnetting Requirements
 같은 Network의 모든 Router의 interface는 동일한 subnet mask를 가짐
 약점 : 낭비되는 host주소 부분이 많음  serial link의 경우 contiguous
 같은 Major Network 의 모든 subnet은 연속성을 가져야 함
2. Classless Routing Overview
 Classless Routing Overview
 Route advertisement 내에 subnet mask를 포함
 Classless Routing은 라우팅 업데이트에 subnet mask를 포함하므로 좀더 정확한 라우팅 테이블을 찾기가 가능함
 Summary routes는 Network 내에서 Manual하게 Control 됨
 Example : OSPF, EIGRP, RIPv2, IS-IS, BGP
 classless subnetting Requirements
 Same Network에 다른 subnet을 가지고 있어도 됨
- VLSM을 지원 (Variable-length subnet masking)
 Host Address의 효율적인 이용 가능
3. Distance Vector Routing Protocol Operations
 Neighbor Router에 Routing Table을 주기적으로 broadcast 함
 Complete routing table을 update 함
 Example : Classful protocols, RIPv2, EIGRP
