静态路由 static route
R1：
configure terminal
interface FastEthernet0/0
ip address 1.1.1.1 255.255.255.0
no shutdown
end
configure terminal
interface loopback 0
ip address 2.2.2.2 255.255.255.0
end
R2：
configure terminal
interface FastEthernet0/0
ip address 1.1.1.2 255.255.255.0
no shutdown
end
configure terminal
interface loopback 0
ip address 3.3.3.3 255.255.255.0
end
配置上述后，还需要配置静态路由，否则从R1无法ping通对端的3.3.3.3，或者从R2无法ping通对端的2.2.2.2
R1:
configure terminal
ip route 0.0.0.0 0.0.0.0 1.1.1.2
end
R1#ping 3.3.3.3
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 3.3.3.3, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 24/29/36 ms
R1#
R2:
configure terminal
ip route 0.0.0.0 0.0.0.0 1.1.1.1
end
R2#ping 2.2.2.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2.2.2.2, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 28/33/44 ms
R2#
R1和R2基本配置完成。
