1 Router 구성 RAM Interfaces LAN Interfaces (e, t, f) WAN Interfaces (s, hssi) Console Auxiliary bootstrap program IOS(Internetwork OS)실행명령어 programactiveconfigfiletablesbuffers NVRAMFlashROM backup config file IOS bootstrapprogram subsetIOS

2 CISCO Router 환경설정 수단 Console 이용 (async serial port) Auxiliary 이용 (auxiliary async serial port) LAN, WAN Interface 를 통한 virtual terminal 이용 (telnet) TFTP 서버를 이용 NMS 를 이용 virtual terminal TFTP server NMS console auxiliary modem

3 Console 을 이용한 라우터 접근 Router con0 is now available Press RETURN to get started User Access Verification Password: Router> Router>enable Password: Router# Router#disable Router> Router>quit console user mode prompt previledged mode prompt

4 Router Modes (1) user mode Router> 제한된 명령어만을 이용 previledged mode Router# 모든 명령어를 이용할 수 있고 configuration file 조정할 수 있음 setup mode 초기 환경설정 previledged mode 에서 명령어 setup 을 입력하면 됨 RXBOOT mode 비밀번호를 잃어버렸거나 Flash 의 OS 가 지워지는 등의 경우 이용 global configuration mode Router(config)# 라우터운영 전체에 영향을 미치는 요소들을 조정할 수 있음. 하위 configuration mode 로 전환할 수 있음 하위 configuration mode Router(config-???)# 영역별 환경 설정

5 라우터 상태 조회 명령어 RAM Interfaces LAN Interfaces (e, t, f) WAN Interfaces (s, hssi) Console Auxiliary bootstrap program IOS(Internetwork OS)실행명령어 programactiveconfigfiletablesbuffers NVRAMFlashROM backup config file IOS bootstrapprogram subsetIOS Router#show version Router#show process [cpu] Router#show protocols Router#show running-config Router#show memory Router#show stacks Router#show buffers Router#show startup-config Router#show config Router#show interface Router#show interface serial 0 Router#show flash

6 라우터의 환경 설정 대상 라우터 이름 운영자 모드 비밀번호 이용자 모드 비밀번호 지원할 네트웍 프로토클 –IP, IPX, DECnet, AppleTalk 등 라우팅 프로토클 –RIP, IGRP, OSPF, BGP 등 기타 네트웍 프로토클에 따른 네트웍 Address Serial link Protocol –HDLC, PPP, X.25, ISDN, Frame-Relay, ATM 등 global environmentinterface environment //NOTE// 이것은 인터넷연결과 관련된 중요부분만을 지적한 것이며 이외에 다양한 것이 있음

7 라우터 초기 Setup Router# setup –setup global parameters hostname, enable password, virtual terminal password, routed protocols,... –setup interface parameters enable interface, network address allocation,.... 관련 명령어 –#show startup-config // show config –#show running-config // write term –#erase startup-config // write erase –#reload

8 Configuration File 수정 방법 NVRAM RAM config terminal show running-config // write term config memory copy running-config startup-config // wirte memory copy tftp running-config // config net copy running-config tftp // wirte net show startup-config // show config 폐기 erase startup-config // write erase

9 Router Modes (2) user modeRouter> previledge modeRouter# global config modeRouter(config)# 하위 config mode interfaceRouter(config-if)# enable config terminal subinterfaceRouter(config-subif)# controllerRouter(config-controller)# map-listRouter(config-map-list)# map-classRouter(config-map-class)# lineRouter(config-line)# routerRouter(config-router)# IPX routerRouter(config-ipx-router)# Route mapRouter(config-route-map)# Ctrl-Z exit

10 Password 및 Router Name 수정 console password –router(config)# line console 0 –router(config-line)# login –router(config-line)# password cisco virtual terminal password –router(config)# line vty 0 4 –router(config-line)# login –router(config-line)# password cisco enable passord –router(config)# enable password cisco –Router(config)#enable secret class enable password 의 암호화 –router(config)# service password-encryption router name –router(config)# hostname smile login banner –smile(config)# banner motd # welcome to smile, in seoul #

11 Router Mode 와 Interface Mode 예 Router Mode –router(config)# router rip –router(config-router)# network 164.124.0.0 –router(config-router)# network 203.252.15.0 –router(config-router)# no network 203.252.15.0 –router(config-router)# exit –router(config)# no router rip –router(config)# exit Interface Mode –router(config)# interface ethernet 0 –router(config-if)# ip address 164.124.1.1 255.255.255.0 –router(config-if)# no ip address 164.124.1.1 255.255.255.0 –router(config-if)# ip address 164.124.2.1 255.255.255.0 –router(config-if)# no shutdown –router(config-if)# exit –router(config)#exit
