题目
第一步:划分网段配置IP地址
R1:
0/0/0:192.168.1.1/30
0/0/1:192.168.1.9/30
L0 :192.168.1.33/28
L1 :192.168.1.49/28
R2:
0/0/0:192.168.1.2/30
0/0/1:192.168.1.5/30
L0 :192.168.1.65/28
L1 :192.168.1.81/28
R3:
0/0/0:192.168.1.10/30
0/0/1:192.168.1.13/30
0/0/2:192.168.1.97/27
R4:
0/0/0:192.168.1.6/30
0/0/1:192.168.1.14/30
0/0/2:192.168.1.17/30
6/0/0:192.168.1.21/30
L0 :192.168.1.129/28
L1 :192.168.1.145/28
R5:
0/0/0:192.168.1.18/30
0/0/1:12.0.0.1/24
0/0/2:192.168.1.22/130
L0 : 192.168.1.161/27
R6:
0/0/0:12.0.0.2/24
L0 :1.1.1.1/24
第二步:配置静态路由实现全网通
以R1为列
[R1]ip route-static 192.168.1.4 30 192.168.1.2
[R1]ip route-static 192.168.1.8 30 192.168.1.10
[R1]undo ip route-static 192.168.1.8 30 192.168.1.10
[R1]ip route-static 192.168.1.96 30 192.168.1.10
[R1]ip route-static 192.168.1.12 30 192.168.1.10
[R1]ip route-static 192.168.1.16 30 192.168.1.2
[R1]ip route-static 192.168.1.20 30 192.168.1.2
[R1]ip route-static 192.168.1.64 30 192.168.1.2
[R1]undo ip route-static 192.168.1.64 30 192.168.1.2
[R1]ip route-static 192.168.1.64 27 192.168.1.2
[R1]ip route-static 192.168.1.128 27 192.168.1.2
[R1]ip route-static 192.168.1.160 27 192.168.1.2
[R1]ip route-static 192.168.1.64 27 NULL0
[R1]ip route-static 192.168.1.128 27 NULL0
[R1]ip route-static 192.168.1.160 27 NULL0
注意:
1,静态路由写法
[Huawei]ip route-static 192.168.3.0 24 192.168.2.2------静态路由
route(路由器)static(静态)------静态路由
192.168.3.0 24------目的地网段
192.168.2.2------下一跳
2,手工汇总
[r2]ip route-static 192.168.1.0 24 12.0.0.1
[r2]ip route-static 192.168.2.0 24 12.0.0.1------两段同时包含在192.168.0.0/22网段都可通过 12.0.0.1接口
[r2]ip route-static 192.168.0.0 22 12.0.0.1
3,路由黑洞
在汇总中,如果包含网络内实际不存在的网段时,可能造成流量的有去无回,浪费链路资源
4,缺省路由
一旦路由黑洞和缺省路由相遇,将100%出现路由环路。
缺省路由就是一条不限定目标的路由条目。缺省路由一定是路由表中所有路由条目都无法匹配时,才最后匹配。
[r1]ip route-static 0.0.0.0 0 12.0.0.2------0.0.0.0可以是任意值,0掩码可以是任意值,12.0.0.2是下一跳
5,空接口路由
用来解决缺省和黑洞相遇出环的问题。 --- 在黑洞路由器上配置一条指向汇总网段的空接口路由到路由表中。
[R1]ip route-static 192.168.1.160 27 NULL0
6,浮动静态路由
通过修改默认的优先级,实现静态路由的备份效果。
[r1]ip route-static 192.168.2.0 24 21.0.0.2 preference 61------手动修改静态路由的优先级
第三步:创建dhcp地址池
[R3]dhcp enable //开启dhcp服务
Info: The operation may take a few seconds. Please wait for a moment.done.
[R3]ip pool pp
Info: It's successful to create an IP address pool.
[R3-ip-pool-pp]network 192.168.1.96 mask 27
[R3-ip-pool-pp]gateway-list 192.168.1.97
[R3-ip-pool-pp]dns-list 114.114.114.114
[R3-ip-pool-pp]q
[R3]int g 0/0/2
[R3-GigabitEthernet0/0/2]dhcp select global //接口上全局宣告
第四步:telent服务
R6 telent R5
R5上面的配置
[R5]aaa
[R5-aaa]local-user admin privilege level 3 password cipher 123456
[R5-aaa]display this
[V200R003C00]
#
aaa
authentication-scheme default
authorization-scheme default
accounting-scheme default
domain default
domain default_admin
local-user admin password cipher %$%$H'+):kp']:))&dX+X)`JyT2y%$%$
local-user admin privilege level 3
local-user admin service-type http
#
return
[R5-aaa]local-user admin service-type telnet
[R5-aaa]q
[R5]user-interface vty 0 4
[R5-ui-vty0-4]authentication-mode aaa
R6上面的配置
<R6>telnet 12.0.0.1
Press CTRL_] to quit telnet mode
Trying 12.0.0.1 ...
Connected to 12.0.0.1 ...
Login authentication
Username:admin
