路由安全：AAA加密本地认证

    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
