CCNP实验,EIGRP实验（一）
1、通过gns3搭建拓扑图，如下
2、根据拓扑图配置各台路由的IP地址，并且使用ping命令确认个路由器的直连接口互通
R1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#int lo 0
R1(config-if)#ip
*Aug 15 01:27:06.272: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up
R1(config-if)#ip add 10.1.1.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#int lo 1
R1(config-if)#ip add
*Aug 15 01:27:39.663: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback1, changed state to up
R1(config-if)#ip add 10.1.2.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#int lo 2
R1(config-if)#ip a
*Aug 15 01:28:01.977: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback2, changed state to up
R1(config-if)#ip add 10.1.3.1 255.255.255.0
R1(config-if)#no sh
R1(config-if)#int lo 3
R1(config-if)#ip add
*Aug 15 01:28:22.046: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback3, changed state to up
R1(config-if)#ip add 10.1.4.1 255.255.255.0
R1(config-if)#no sh
R1(config)#int s2/1
R1(config-if)#ip add 172.16.1.1 255.255.255.252
R1(config-if)#no sh
配置R1后通过show命令查看端口状态，
3、同样将R2 ,R3 的端口配置好IP地址
R2#conf t
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#int s2/0
R2(config-if)#ip add 172.16.1.2 255.255.255.252
R2(config-if)#no sh
R2(config-if)#
*Aug 15 01:34:30.307: %LINK-3-UPDOWN: Interface Serial2/0, changed state to up
*Aug 15 01:34:31.311: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/0, changed state to up
R2(config-if)#int s2/1
R2(config-if)#ip add 172.16.1.5 255.255.255.252
R2(config-if)#no sh
R2(config-if)#int lo
*Aug 15 01:35:02.865: %LINK-3-UPDOWN: Interface Serial2/1, changed state to up
*Aug 15 01:35:03.867: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/1, changed state to up
R2(config-if)#int lo 0
R2(config-if)#ipadd
*Aug 15 01:35:05.343: %LINEPROTO-5-UPDOWN: Line protocol on Interface Loopback0, changed state to up
R2(config-if)#ip add 131.131.1.1 255.255.0.0
R2(config-if)#no sh
R2(config-if)#
*Aug 15 01:35:26.237: %LINEPROTO-5-UPDOWN: Line protocol on Interface Serial2/1, changed state to down
R3的端口请自行配置！
配置完成后通过show ip int bri ，查看端口信息
4、通过ping命令来确保直连端口的的连通性
1、在3台路由器上配置EIGRP协议，自制系统号为50,
R1配置如下
2、R2配置如下,从图上可以看到，当配置了network 172.16.0.0 ，R1和R2的邻居起来了！
3、R3请自行配置，配置完成后通过命令show ip route查看各个路由器的路由表。
R1路由表如下，可以看到R2和R3的路由条目
4、R2路由表如下
5、R3路由表如下
6、最后通过ping命令来查看连通性
R1#ping 192.168.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 19/19/20 ms
R1#ping 172.16.1.6
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.1.6, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 20/20/20 ms
R1#
