实验过程中严禁使用静态路由。
一.基本配置:(3)
3、 R2 起用 LOOPBACK 1:2.2.0.2/24; LOOPBACK 2:2.2.1.2/24;
LOOPBACK 3:2.2.2.2/24; LOOPBACK 4:2.2.3.2/24
4、 R1 起用 LOOPBACK 1:1.1.1.4/24; LOOPBACK 2:1.1.2.4/24;
LOOPBACK 3:1.1.3.4/24; LOOPBACK 4:1.1.4.4/24
LOOPBACK 5:1.1.5.4/24
二、 链路配置: (5)
1、 R3—R2 的链路使用 PPP封装,CHAP 认证。
2、 R4—R3 的链路使用 PPP封装,PAP认证。
3、 都为单向认证,R3 为认证的 SERVER 端。CHAP 认证的密码为”CISCO”,PAP
认证的密码为”HP”。
三、OSPF(12)
1、 R2 公告 lo1:2.2.0.2/24----lo4:2.2.3.2/24到 AREA1,在 R3 上要收到汇总路由。
2、 AREA 0使用 MD5 的区域认证。密码为“cisco”, key使用“10”
3、 AREA 1 路由要最简化。
4、 将 RIP 重分布到 OSPF 中,只允许 12.1.1.0/24 进入 OSPF 区域。并标注为
TAG10.
5、 使用 X.X.X.X 作为 OSPF 路由器的 ROUTER-ID. X 为路由器的下标。
6、 R4 和 R3 的回环接口都公告到 OSPF 的 AREA0.
四、RIP(R2 的 LOOPBACK 0 不能公告在 RIP 中,否则扣 10 分)
1、 R1 运行 RIP V2,R2 运行 RIP V1。
2、 R2 和 R1 之间使用单播更新。
3、 R2 只接受来自 R1 的 lo0的路由和 1.1.X.0/24,其中 X 为单数。 例如: 1.1.3.0/24
五、EIGRP
1、 R4 上做双向重分布。
2、 R5 上从 R4上学到的路由条目要是负载均衡的。
六、NAT
1、 地址池 12.1.1.10/24—12.1.1.15/24
2、 所有 23,34.Y.0.0/16 网段设备要可以 PING 通 R1 的 S1/1 接口
配置要点
中间有些地址做了些许变化,但不影响需求的实现。

可以看到实现了负载均衡,由于上边修改了K值和带宽。

在R3上用23.1.1.3接口ping12.1.1.1并查看R2的NAT转换表:
R3#ping 12.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 12.1.1.1, timeout is 2 seconds:
