A에 대한 설정 ( But 나는 모두 설정할 것이다.)
1. 라우터 이름은 Router_A를 사용합니다.
2. Enable password는 cisco를 사용합니다.
3. 시리얼 인터페이스, 이더넷 인터페이스 IP 설정을 합니다.
4. 스태틱 라우팅을 사용합니다.
5. 150.100.0.0(255.255.0.0) 네트워크를 접속할 수 있어야 합니다.
6. 나머지 모든 트래픽은 디폴트로 인터넷 쪽을 나갈 수 있도록 구성합니다.

디폴트 라우트 구성시 주의점!!
Router#ip defalut-network 203.240.10.0
이 명령어 사용시 규칙이 있다.
첫번째 규칙 - 클래스 준수해야한다.
두번째 규칙 - rip 프로토콜 사용시 돌아가고 있는 네트워크로 구성해야한다. IGRP 는 반대다. 다른 라우팅 프로토콜은 잘모르겟다..
