CCIE学习——OSPF配置

配置拓扑图：

配置要求：

1）证明在不同路由器上OSPF的PID不用匹配也可以建立邻接关系。 2）使用network命令来匹配借口，从而在网络10.0.0.0内触发邻接路由器发现进程。

3）配置S1的RID为7.7.7.7。

4）在骨干LAN上设置合适的优先权值以使得S1和S2成为DR/BDR。

5）在骨干LAN上配置dead间隔为最小（1秒），它是hello间隔的4倍，所以hello间隔为250毫秒。

6）配置区域3为完全NSSA区域，区域4为完全桩区域，区域5为桩区域。 具体配置： 1）R1的配置：

interface FastEthernet0/0

ip address 10.1.1.1 255.255.255.0

ip ospf dead-interval minimal hello-multiplier 4 !

router ospf 1

area 3 nssa no-summary area 4 stub no-summary area 5 stub

network 10.1.0.0 0.0.255.255 area 0 network 10.3.0.0 0.0.255.255 area 3 network 10.4.0.0 0.0.255.255 area 4 network 10.5.0.0 0.0.255.255 area 5

2）R2的配置：

interface FastEthernet0/0

ip address 10.1.1.2 255.255.255.0

ip ospf dead-interval minimal hello-multiplier 4 !

router ospf 2 area 5 stub

network 10.1.0.0 0.0.255.255 area 0 network 10.5.25.2 0.0.0.0 area 5 3）R3的配置： router ospf 1

area 3 nssa no-summary

network 10.0.0.0 0.255.255.255 area 3 4）R4的配置： router ospf 1

area 4 stub no-summary

network 10.0.0.0 0.255.255.255 area 4 5）S1的配置： interface Vlan1

ip address 10.1.1.3 255.255.255.0

ip ospf dead-interval minimal hello-multiplier 4 ip ospf priority 255 !

router ospf 1 router-id 7.7.7.7

network 10.1.0.0 0.0.255.255 area 0 6）S2的配置： interface Vlan1

ip address 10.1.1.4 255.255.255.0

ip ospf dead-interval minimal hello-multiplier 4 ip ospf priority 254 !

router ospf 1

network 10.0.0.0 0.255.255.255 area 0 ●OSPF的开销以及怎样重启OSPF进程 IOS确定OSPF接口开销的方法： 1）使用neighbor neighbor cost value命令对每台邻接路由器设置开销（对于允许使用neighbor命令的网络类型）。

2）使用ip ospf cost value接口子命令对每个接口设置开销。 3）开销默认为OSPF参考带宽（默认108）/接口带宽（bps）。

4）在OSPF进程下使用ospf auto-cost reference-bandwidth value命令设置OSPF参考带宽。

注意：IOS的接口带宽的单位是kbps，而auto-cost reference-bandwidth命令的单位是Mbps。当两数相除时，所得结果会向下取整，如100/1.544=64。

如果要重启OSPF进程，可以使用clear ip ospf process命令，路由器会要求你确认，输入“y”即表示确认重启。

●OSPF网络命令的替代

从Cisco IOS 12.3(11)T开始，OSPF的配置中可以完全省去network命令部分，取而代之的是ip ospf process-id area area-id接口子命令。新命令可在接口上激活OSPF并选择区域。例如，前面例子中的network 10.3.0.0 0.0.255.255 area 3命令可以用S0/0.1和e0/0接口上的命令ip ospf 1 area 3替换。

如果使用了从IP地址，network和ip ospf area命令会有一些细微的差别。当使用network命令的时候，OSPF只将匹配命令的从IP子网广播为桩网络，而ip ospf area命令则使所配置接口上的所有从子网广播为桩网络（除非配置了secondaries none参数）。

区域间和外部路由汇总案例 主题关键词：无线网络破解

CISCO允许对地址进行汇总，以通过限制区域间通告的路由来达到节省资源的目的。 CISCO路由器支持两种类型的地址汇总：区域间汇总和外部路由汇总。区域间汇总用于在区域间汇总地址，而外部汇总用于收集到某个Cisco CCNP培训域中的一系列外部路由的汇总。 5.jpg (30.79 KB)2009-10-25 20:38路由器A将通过V。35交叉电缆连接到路由器B上。路由器B作为DCE为路由器A提供时钟。B和C通过以太网集线器连接。C通过交叉电缆连接到 D上。C作为DCE为D提供时钟。D和E通过以太网集线器连接BT无线网络破解教程B和C上的第二个以太网接口将不连到任何地方，所以需要禁用其活跃状 态。这里使用以太网接口代替回送接口的原因是，回送接口在区域边界间是作为/32位网络通告的。 RIP运行D和E之间；E将通告所有连接的子网。D将把学习到的RIP路由重分布到OSPF中，这里不使用相互的重分布，因为不需要它来验证汇总。但是， 如果你希望E能够看见OSPF网络，就需要加上它。所有IP地址分配如图。 //router a int e0 ip addr 192.1.1.2 255.255.255.0 int s0 ip addr 152.1.2.1 255.255.255.252 router ospf 64 network 152.1.2.0 0.0.0.255 area 1 //指定运行OSPF的接口以及该接口位于的区域 //router b int e1/0 ip addr 152.1.1.129 255.255.255.192 no keepalive int e0/0 ip addr 152.1.1.1 255.255.255.128 int s0/0 ip addr 152.1.2.2 255.255.255.252 no ip direct-broadcast no ip mroute-cache no fair-queue clockrate 1000000 router ospf 64 netw 152.1.1.0 0.0.0.255 area 0 netw 152.1.2.0 0.0.0.255 area 1 //router c int e1/0 ip addr 152.1.1.193 255.255.255.192 no ip direct-broadcast no keepalive int e0/0思科培训团购 ip addr 152.1.1.2 255.255.255.128 no ip direct-broadcast int s0/0 ip addr 152.1.3.2 255.255.255.252 no ip direct-broadcast no ip mroute-cache no fair-queue clockrate 1000000 router ospf 64 netw 152.1.1.0 0.0.0.255 area 0 netw 152.1.3.0 0.0.0.255 area 2 //router d int e0 ip addr 130.1.4.1 255.255.255.0 no ip direct-broadcast int s0 ip addr 152.1.3.1 255.255.255.252 no ip direct-broadcast ip ospf interface-retry 0 router ospf 64 redistribute rip metric 10 sunets //重分布RIP到OSPF中(对于此实

实验：EIGRP浮动汇总路由

2009-06-22 01:42:14 实验拓扑：

接口连接： Router1 S0/0 <----> Router2 S0/0 Router2 S0/1 <----> Router3 S0/0 Router1 S0/1 <----> Router4 S0/0 Router3 S0/1 <----> Router4 S0/1 VPCS V0/1 <----> Router1 E1/0 VPCS V0/2 <----> Router3 E1/0

实验原理： 在R1\\R2\\R3\\R4上均运行EIGRP路由协议。R4通过S0/1向R3通告一条0.0.0.0 0.0.0.0的汇总路由，并将这条浮动路由的管理距离设置为250，于是在网络连通的情况下R3上到达200.1.1.0/24网段的路由经过R2，而 在R2与R3链路故障的时候，通过R3前往200.1.1.0/24的数据包会通过R4（R3拓扑表中，默认路由由A变为P） 关键配置： R1: interface Serial0/0 ip address 192.168.1.1 255.255.255.0 serial restart-delay 0 !

interface Serial0/1

ip address 192.168.3.1 255.255.255.0

interface Serial0/1

ip address 192.168.4.1 255.255.255.0

ip summary-address eigrp 100 0.0.0.0 0.0.0.0 250（向R3通过默认路由，管理距离高于EIGRP默认值）! router eigrp 100 network 192.168.3.0 network 192.168.4.0

2009-04-27 18:31:55

一、目的：在通过帧中继网络通信的两台路由器之间实现验证功能（封装类型为帧中继的串行接口不能进行PPP验证，使用Virtual-Template来实现）。 二、实验拓扑图：

三、具体配置： 1、路由器R1:

username R1 password 0 00830725 ! !

interface Serial0/0 no ip address

encapsulation frame-relay IETF serial restart-delay 0

frame-relay interface-dlci 102 ppp Virtual-Template10 （将虚拟模板与本地dlci值关联）

no frame-relay inverse-arp ! !

interface Virtual-Template10 bandwidth 1544

ip address 192.168.1.1 255.255.255.0

ppp authentication pap ! 2、路由器R2: !

interface Serial0/0 no ip address

encapsulation frame-relay IETF serial restart-delay 0

frame-relay interface-dlci 201 ppp Virtual-Template10 （将虚拟模板与本地dlci值关联）

no frame-relay inverse-arp ! !

interface Virtual-Template10 bandwidth 1544

ip address 192.168.1.2 255.255.255.0

ppp pap sent-username R1 password 0 00830725 !

四、验证

1. sh ip int bri (查看接口状态)

virtual-template接口的状态永远为down/down，主要看virtual-template生成的virtual-access的值为UP/UP则接口启用。 2.ping

3.sh frame-relay pvc

通过Cisco SDM 登录思科路由器

2009-03-25 02:38:39

这个实验的拓扑如下：

使用的实验工具是dynamipsGUI和WMware虚拟出来的网卡（大家看到的拓扑实际上是路由器与虚拟网桥的桥接）。

实验很简。要注意的是，在路由器第一次启动后，在配置好F0/0的地址并启动接口后，在主机上设置IP并使用ping命令测试与路由器是否建立链接。如果一切正常，则启动SDM，输入路由器与主机相连的接口地址，这样大家就进入SDM的界面了：

出于安全考虑，也为了下次登录，我们要设定用户名和密码（previlege为15）。用户名和密码的设定方法会在下面给大家介绍。

好，先通过SDM登录路由器（有些IOS版本是不支持SDM的）： 哦，还要在IE浏览器上做一下设置，就是在 工具-》选项-》高级的“安全”目录下，将“允许活动的内容在我的计算机的文件中运行”打勾！

配置用户帐号。选“配置”然后选择“其他任务”，打开“路由器访问”，双击“用户帐号/视图”，如下图：

根据不同来源地址的流量，通过策略路由选择不同的出口： 在这个实验中，源地址为211.141.1.0/24的数据必.. 类别：路由|阅读(801)|回复(2)|赞(0)阅读全文>> 原创

实验：VLAN环境下DHCP的配置

2008-11-16 13:46:41

虚拟情景：

企业有多个部门，这些部门的主机都连接在一台多接口交换机上，不同的部门分别被划分在不同的VLAN中，为了尽快部署，要求使用DHCP对这些属于不同VLAN的主机进行IP地址分配。 实验拓扑如下：  ..

CCNP路由重分发（四）EIGRP-to-ISIS

2008-10-24 19:35:55

这个实验是关于EIGRP和ISIS网络之间的路由重分发。ISIS也属于链路状态路由，采用的也是分层结构，但与OSPF不同的是ISIS每一个路由器只能属于一个区域，而OSPF则可以将同一个路由器上的不同接口分配到不同的区域中.. 类别：路由|阅读(477)|回复(0)|赞(0)阅读全文>> 原创

CCNP路由重分发（三）EIGRP-to-OSPF

2008-10-24 19:27:21

这个实验做一下EIGPR网络与OSPF网络之间的路由重分发，实验拓扑如下：

实验用的时小凡的模拟器，路由器连接拓扑如下表： Router1 S0/0 <----> Router2 S0/1 Router2 S0/0 <----> Router3 S0/1 Router3 S0/0 <----> Router4 S0/1

为配置路由重分发时各路由器上的路由表状况： R1#sh ip route ！
