静态路由默认路由的配置

静态路由实验

负载均衡的一点是个人理解，有不正确之处欢迎批评指正。

R1配置:

s0/0/0口：193.1.1.9/30(本地) next-hop 193.1.1.10/30 point-to-point link
F0/0设置子接口：F0/0.1 172.17.115.1/24 VLAN1 F0/0.5 172.17.110.1/24 VLAN6
静态路由配置：
ip route 192.168.1.0 255.255.255.0 193.1.1.10
ip route 192.168.2.0 255.255.255.0 193.1.1.10
ip route 193.1.1.16 255.255.255.252 193.1.1.10
ip route 1.1.1.0 255.255.255.0 193.1.1.10
ip route 10.10.0.0 255.255.0.0 193.1.1.10

S1配置：VLAN 1 ,VLAN 6 F0/10 F0/11
PC1:172.17.115.11/24
PC2:172.17.110.11/24

R2配置: DCE
LOOPBACK口：192.168.1.1/24   192.168.2.1/24
s0/0/0口：193.1.1.10/30(本地)   next-hop 193.1.1.9/30 point-to-point link
s0/0/1口：193.1.1.17/30(本地)   next-hop 193.1.1.18/30 point-to-point link
静态路由配置：
ip route 172.17.115.0 255.255.255.0 193.1.1.9 1/2（管理距离，如有备用路由时）
ip route 172.17.110.0 255.255.255.0 193.1.1.9
ip route 1.1.1.0 255.255.255.0 193.1.1.18 permanent (加此参数，则为静态路由使用的接口出现故障，仍将把路由保存在跌幅表中)
ip route 10.10.2.0 255.255.0.0 193.1.1.18

R3配置:默认路由

LOOP口：1.1.1.1/24
F0/0口:10.10.2.1/16
s0/0/1口：193.1.1.18/30(本地) next-hop 193.1.1.17/30 point-to-point link
静态路由配置：
默认路由 ip route 0.0.0.0 0.0.0.0 193.1.1.17
SERVER:10.10.9.61

最终实现全网互联。

R1配置:Router>ena
Router#conf t
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#int f0/0
Router(config-if)#no shu 需要先把接口启用

%LINK-5-CHANGED: Interface FastEthernet0/0, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed state to up

Router(config-if)#int f0/0.1 创建并进入子接口f0/0.1

%LINK-5-CHANGED: Interface FastEthernet0/0.1, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.1, changed state to up        子接口创建即启动，不需要手动配置。

Router(config-subif)#encapsulation dot1q 1      配置封装为dot1q。并与VLAN 1相关联
Router(config-subif)#ip add 172.17.115.1 255.255.255.0   配置子接口IP

Router(config-subif)#int f0/0.5

%LINK-5-CHANGED: Interface FastEthernet0/0.5, changed state to up

%LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0.5, changed state to up
Router(config-subif)#encapsulation dot1q 6
Router(config-subif)#ip add 172.17.110.1 255.255.255.0
Router(config-subif)#exi
Router(config)#int s0/0/0
Router(config-if)#ip add 193.1.1.9 255.255.255.252
Router(config-if)#no shu

%LINK-5-CHANGED: Interface Serial0/0/0, changed state to down
Router(config-if)#exi
Router(config)#ip route 192.168.1.1 255.255.255.0 193.1.1.9
%Inconsistent address and mask 出错是因为需配置目的网段，非主机地址
Router(config)#ip route 192.168.1.0 255.255.255.0 193.1.1.10 通过下一跳IP193.1.1.10到达192.168.1.0网段的静态路由。
Router(config)#ip route 192.168.1.0 255.255.255.0 193.1.1.10 2 管理距离默认为1，设置为2即为备用路由。

Router(config)#ip route 192.168.1.0 255.255.255.0 193.1.1.10 1 管理距离默认为1，设置为1或者不设置即实现负载均衡。负载均衡这点是个人理解，静态路由基于管理距离进行路由。

Router(config)#ip route 192.168.2.0 255.255.255.0 193.1.1.10
Router(config)#ip route 193.1.1.16 255.255.255.252 193.1.1.10
Router(config)#ip route 1.1.1.0 255.255.255.0 193.1.1.10
Router(config)#ip route 10.10.2.0 255.255.255.0 193.1.1.10
