静态路由配置（两条链路之间做负载均衡）

掌握目标一、配置设备名称与 IP 地址：二、配置静态路由三、配置浮动路由用于备份四、配置默认路由一、配置设备名称与 IP 地址： (ccieh3c.qzone.qq.com)R1：<Huawei>system-viewEnter system view, return user view with Ctrl+Z.[Huawei]sysname R1[R1]interface g0/0/1[R1-GigabitEthernet0/0/1]ip address 202.100.1.1 255.255.255.0quit[R1]interface g0/0/2[R1-GigabitEthernet0/0/2]ip add 202.100.2.1 255.255.255.0quit[R1-GigabitEthernet0/0/1]int lo 0 =====创建环回接口[R1-LoopBack0]ip add 1.1.1.1 255.255.255.255[R1-LoopBack0]quit[R1]display current-configuration interface =====显示接口信息#interface GigabitEthernet0/0/0#interface GigabitEthernet0/0/1ip address 202.100.1.1 255.255.255.0#interface GigabitEthernet0/0/2ip address 202.100.2.1 255.255.255.0#interface NULL0#interface LoopBack0ip address 1.1.1.1 255.255.255.255R2：[R2]interface g0/0/1[R2-GigabitEthernet0/0/1]ip add 202.100.1.2 255.255.255.0[R2-GigabitEthernet0/0/1]int g0/0/0[R2-GigabitEthernet0/0/0]ip add 202.100.3.2 255.255.255.0[R2-GigabitEthernet0/0/0]int lo 0[R2-LoopBack0]ip ad 2.2.2.2 255.255.255.255[R2-LoopBack0]quitR3：[R3]int g0/0/2[R3-GigabitEthernet0/0/2]ip add 202.100.2.3 255.255.255.0[R3-GigabitEthernet0/0/2]int g0/0/0[R3-GigabitEthernet0/0/0]ip add 202.100.3.3 255.255.255.0[R3-GigabitEthernet0/0/0]int lo 0[R3-LoopBack0]ip add 3.3.3.3 255.255.255.255<R1>ping -c 2 202.100.1.2 =====ping 两个数据包PING 202.100.1.2: 56 data bytes, press CTRL_C to breakReply from 202.100.1.2: bytes=56 Sequence=1 ttl=255 time=10 msReply from 202.100.1.2: bytes=56 Sequence=2 ttl=255 time=1 ms--- 202.100.1.2 ping statistics ---2 packet(s) transmitted2 packet(s) received0.00% packet lossround-trip min/avg/max = 1/5/10 ms<R1>ping -c 2 202.100.2.3PING 202.100.2.3: 56 data bytes, press CTRL_C to breakReply from 202.100.2.3: bytes=56 Sequence=1 ttl=255 time=20 msReply from 202.100.2.3: bytes=56 Sequence=2 ttl=255 time=10 ms--- 202.100.2.3 ping statistics ---2 packet(s) transmitted2 packet(s) received0.00% packet lossround-trip min/avg/max = 10/15/20 ms<R1>display ip routing-table ====查看路由表Route Flags: R -
