h3c华三设备的静态路由配置实例
首先配置R1 R2 R3的基本配置,为相应的接口配置合理的IP 地址。同一根网线上连接的两个路由器,要配置相同的网络位,不同的主机位因为他们是位于同一个网络的不同设备。
R1配置:
- Router>enable
- Router#config ter
- Router(config)#line console 0
- Router(config-line)#exec-timeout 0 0
- Router(config-line)#logging synchronous
- Router(config-line)#exit
- Router(config)#no ip domain-lookup
- Router(config)#ho R1
- R1(config)#interface loopback 0
- R1(config-if)#ip address 1.1.1.1 255.255.255.255
- R1(config-if)#no shutdown
- R1(config-if)#exit
- R1(config)#interface loopback 1
- R1(config-if)#ip address 1.1.2.1 255.255.255.255
- R1(config-if)#no shutdown
- R1(config-if)#exit
- R1(config)#interface loopback 2
- R1(config-if)#ip address 1.1.3.1 255.255.255.255
- R1(config-if)#no shutdown
- R1(config-if)#exit
- R1(config)#interface loopback 3
- R1(config-if)#ip address 1.1.4.1 255.255.255.255
- R1(config-if)#no shutdown
- R1(config-if)#exit
- R1(config)#interface f0/0
- R1(config-if)#ip address 12.1.1.1 255.255.255.0
- R1(config-if)#no shutdown
- R1(config-if)#exit
R2配置:
- Router>enable
- Router#config terminal
- Router(config)#line console 0
- Router(config-line)#exec-timeout 0 0
- Router(config-line)#logging synchronous
- Router(config-line)#exit
- Router(config)#no ip domain-lookup
- Router(config)#ho R2
- R2(config)#interface f0/0
- R2(config-if)#ip address 12.1.1.2 255.255.255.0
- R2(config-if)#no shutdown
- R2(config-if)#exit
- R2(config)#interface f0/1
- R2(config-if)#ip address 23.1.1.2 255.255.255.0
- R2(config-if)#no shutdown
- R2(config-if)#exit
- R2(config)#interface loopback 0
- R2(config-if)#ip address 2.2.2.2 255.255.255.255
- R2(config-if)#no shutdown
- R2(config-if)#exit
R3配置:
- Router>enable
- Router#config terminal
- Router(config)#line console 0
- Router(config-line)#exec-timeout 0 0
- Router(config-line)#logging synchronous
- Router(config-line)#exit
- Router(config)#no ip domain-lookup
- Router(config)#ho R3
- R3(config)#interface f0/1
- R3(config-if)#ip address 23.1.1.3 255.255.255.0
- R3(config-if)#no shutdown
- R3(config-if)#exit
- R3(config)#interface lo0
- R3(config-if)#ip address 3.3.3.3 255.255.255.255
- R3(config-if)#no shutdown
- R3(config-if)#exit
接下来在R1 R2 R3上配置静态路由,由于一个路由器的接口配置了IP 地址之后,对于路由器而言,就产生了到达改网络的路径,就是我们所说的直连路径。因此我们仅仅需要配置到达网络中其他地方(非直连)网络的路径即可。
R1配置:
对于R1而言直连路经就是路由表中打C 标记的路由,而2.2.2.2/32,3.3.3.3/32,23.1.1.0/24
这几条路径R1的路由表中没有(这些是非直连路径),因此需要针对这几条路径进行配置.
- R1#sho 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
- E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
- i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
- * - candidate default, U - per-user static route, o - ODR
- P - periodic downloaded static route
- Gateway of last resort is not set
- 1.0.0.0/32 is subnetted, 4 subnets
- C 1.1.1.1 is directly connected, Loopback0
- C 1.1.2.1 is directly connected, Loopback1
- C 1.1.3.1 is directly connected, Loopback2
- C 1.1.4.1 is directly connected, Loopback3
- 12.0.0.0/24 is subnetted, 1 subnets
- C 12.1.1.0 is directly connected, FastEthernet0/0

- spacer.gifR1(config)#ip route 3.3.3.3 255.255.255.255 12.1.1.2 有谁帮我把数据转发到目的地---下一跳地址
- R1(config)#ip route 23.1.1.0 255.255.255.0 12.1.1.2
- spacer.gifR1(config)#ip route 2.2.2.2 255.255.255.255 f0/0 要去那里,该从那个接口把数据发出去—出接口
R2配置:
对于R2而言 只有 1.1.1.1-----1.1.2.1----1.1.3.1----1.1.4.1以及3.3.3.3 是不直接相连的(非直连),因此只需要针对这些网段写静态路由就可以了,对于1.1.1.1----1.1.4.1的这四条路径,可以用汇总的方式,以一条命令去完成对于四条命令的匹配.---进行汇总.同时注意,汇总的时候,有可能将1.1.5.1等等不存在的网段也汇总进去了,因此注意,在R1上(应为汇总的1.1.1.1—1.1.4.1 是R1上的路径)部署黑洞路由.
R2(config)#ip route 1.1.0.0 255.255.248.0 12.1.1.1
R2(config)#ip route 3.3.3.3 255.255.255.255 23.1.1.3
R1配置:
R1(config)#ip route 1.1.0.0 255.255.248.0 null 0
R3配置:
在R3上 我们可以认为R3上网络的终点,因此对于R3而言,到网络的任意一点,都可以被缺省路由匹配.
R3(config)#ip route 0.0.0.0 0.0.0.0 23.1.1.2
检查路由表,看看路径是否都齐全.
R1 R2 R3要有到达 1.1.1.1—1.1.2.1---1.1.3.1---1.1.4.1以及12.1.1.0/24;23.1.1.0/24;
2.2.2.2/32;3.3.3.3/32的路径.
