[CCNA]패킷트레이서 기초 1(Router - Router)

1. 라우터 케이블 연결

- 같은 계층 장비이므로 크로스 케이블로 연결

 

2. Hostname 설정

- Router 1 -> R-1

Router>en
Router#conf t
Router(config)#hostname R-1

- Router 2 -> R-2

Router>en
Router#conf t
Router(config)#hostname R-2

 

3. IP 주소 설정

- Router 1 -> 10.1.1.1

Router>en
Router#conf t
R-1(config)#do sh ip int br
Interface              IP-Address      OK? Method Status                Protocol

4. 서로 Ping 여부 확인

- Router 1

R-1(config)#do ping 10.1.1.2

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

R-1(config)#

- Router 2

R-2(config)#do ping 10.1.1.1

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 0/0/0 ms

5. 라우팅 테이블 정보 확인

- Router 1

R-1(config)#do sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
       D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
       N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
