静态路由实验

1. 全网所有网段全部基于192.168.1.0/24划分所得
2. R1-R4每台设备均有两个环回
3. 全网可达
4. 尽量减少路由条目，且防止环路
5. R5的环回5.5.5.5/24不能出现在其他设备的路由表中

一、ip地址的划分

二、配置端口IP与环回IP地址

R1： Ethernet0/0/0 ip address 192.168.1.1 255.255.255.252
Ethernet0/0/1 ip address 192.168.1.5 255.255.255.252

interface LoopBack1 ip address 192.168.1.33 255.255.255.240
interface LoopBack2 ip address 192.168.1.49 255.255.255.240

R2： Ethernet0/0/0 ip address 192.168.1.2 255.255.255.252#
Ethernet0/0/1 ip address 192.168.1.9 255.255.255.252

interface LoopBack1 ip address 192.168.1.65 255.255.255.240
interface LoopBack2 ip address 192.168.1.81 255.255.255.240

R3： Ethernet0/0/0 ip ddress 192.168.1.10 255.255.255.252
Ethernet0/0/1 ip address 192.168.1.14 255.255.255.252
GigabitEthernet0/0/0 ip address 192.168.1.21 255.255.255.252
GigabitEthernet0/0/1 ip address 192.168.1.17 255.255.255.252

interface LoopBack1 ip address 192.168.1.97 255.255.255.240
interface LoopBack2 ip address 192.168.1.113 255.255.255.240

R4： Ethernet0/0/0 ip address 192.168.1.13 255.255.255.252
Ethernet0/0/1 ip address 192.168.1.6 255.255.255.252

interface LoopBack1 ip address 192.168.1.129 255.255.255.240
interface LoopBack2 ip address 192.168.1.145 255.255.255.240

R5： Ethernet0/0/0 ip address 192.168.1.22 255.255.255.252
Ethernet0/0/1 ip address 192.168.1.18 255.255.255.252

interface LoopBack1 ip address 5.5.5.5 255.255.255.0

三、配置静态路由，添加缺省路由

R1：
ip route-static 0.0.0.0 0.0.0.0 192.168.1.2
ip route-static 0.0.0.0 0.0.0.0 192.168.1.6

查看已配置的端口IP

查看已配置的静态路由

测试直连

目前全网可达
三，备份

空接口防环路由

关闭R3 g0/0/1 端口，使其走千兆路线

打开则又走百兆
