第一步：预配置
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip domain-lo
Router(config)#
Router(config)#line con 0
Router(config-line)#no exec-t
Router(config-line)#logg s
Router(config-line)#ho R1
R1(config)#inter lo0
R1(config-if)#ip add 1.1.1.1 255.255.255.0
R1(config-if)#inter e0/0
R1(config-if)#ip add 192.168.1.1 255.255.255.0
R1(config-if)#no shut
Router>en
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#no ip domain-lo
Router(config)#
Router(config)#line con 0
Router(config-line)#no exec-t
Router(config-line)#logg s
Router(config-line)#ho R2
R2(config)#inter lo0
R2(config-if)#ip add 2.2.2.2 255.255.255.0
R2(config-if)#inter e0/0
R2(config-if)#ip add 192.168.1.2 255.255.255.0
R2(config-if)#no shut
第二步：配置本地认证：
R1(config)#aaa new
R1(config)#aaa new-model
R1(config)#aaa authentication login default local
R1(config)#username norvel password norvel
第三步：调式;
R1#ping 192.168.1.2
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.2, timeout is 2 seconds:
.!!!!
Success rate is 80 percent (4/5), round-trip min/avg/max = 28/40/64 ms
R1#debug aaa authentication
