配置OSPF基本功能示例.doc

配置OSPF基本功能示例介绍OSPF基本功能的配置过程，包括在各路由器上使能OSPF、指定不同区域内的网段。组网需求如图1所示，所有的路由器都运行OSPF，并将整个自治系统划分为三个区域，其中RouterA和RouterB作为ABR来转发区域之间的路由。配置完成后，每台路由器都应学到AS内的到所有网段的路由。图1 配置OSPF基本功能组网图 配置思路采用如下的思路配置OSPF基本功能：1. 在各路由器上使能OSPF。2. 指定不同区域内的网段。数据准备为完成此配置例，需准备如下的数据： RouterA的router id 1.1.1.1，运行的OSPF进程号1，在区域0的网段192.168.0.0/24，在区域1的网段192.168.1.0/24。 RouterB的router id 2.2.2.2，运行的OSPF进程号1，在区域0的网段192.168.0.0/24，在区域2的网段192.168.2.0/24。 RouterC的router id 3.3.3.3，运行的OSPF进程号1，在区域1的网段192.168.1.0/24，172.16.1.0/24。 RouterD的router id 4.4.4.4，运行的OSPF进程号1，在区域2的网段192.168.2.0/24，172.17.1.0/24。 RouterE的router id 5.5.5.5，运行的OSPF进程号1，在区域1的网段172.16.1.0/24。 RouterF的router id 6.6.6.6，运行的OSPF进程号1，在区域2的网段172.17.1.0/24。操作步骤1. 配置各接口的IP地址（略） 2. 配置OSPF基本功能 # 配置RouterA。RouterA router id 1.1.1.1RouterA ospfRouterA-ospf-1 area 0RouterA-ospf-1-area-0.0.0.0 network 192.168.0.0 0.0.0.255RouterA-ospf-1-area-0.0.0.0 quitRouterA-ospf-1 area 1RouterA-ospf-1-area-0.0.0.1 network 192.168.1.0 0.0.0.255RouterA-ospf-1-area-0.0.0.1 quit# 配置RouterB。RouterB router id 2.2.2.2RouterB ospfRouterB-ospf-1 area 0RouterB-ospf-1-area-0.0.0.0 network 192.168.0.0 0.0.0.255RouterB-ospf-1-area-0.0.0.0 quitRouterB-ospf-1 area 2RouterB-ospf-1-area-0.0.0.2 network 192.168.2.0 0.0.0.255RouterB-ospf-1-area-0.0.0.2 quit# 配置RouterC。RouterC router id 3.3.3.3RouterC ospfRouterC-ospf-1 area 1RouterC-ospf-1-area-0.0.0.1 network 192.168.1.0 0.0.0.255RouterC-ospf-1-area-0.0.0.1 network 172.16.1.0 0.0.0.255RouterC-ospf-1-area-0.0.0.1 quit# 配置RouterD。RouterD router id 4.4.4.4RouterD ospfRouterD-ospf-1 area 2RouterD-ospf-1-area-0.0.0.2 network 192.168.2.0 0.0.0.255RouterD-ospf-1-area-0.0.0.2 network 172.17.1.0 0.0.0.255RouterD-ospf-1-area-0.0.0.2 quit# 配置RouterE。RouterE router id 5.5.5.5RouterE ospfRouterE-ospf-1 area 1RouterE-ospf-1-area-0.0.0.1 network 172.16.1.0 0.0.0.255RouterE-ospf-1-area-0.0.0.1 quit# 配置RouterF。RouterF router id 6.6.6.6RouterF ospfRouterF-ospf-1 area 2RouterF-ospf-1-area-0.0.0.2 network 172.17.1.0 0.0.0.255RouterF-ospf-1-area-0.0.0.2 quit3. 验证配置结果 # 查看RouterA的OSPF邻居。RouterA display ospf peer OSPF Process 1 with Router ID 1.1.1.1 Neighbors Area 0.0.0.0 interface 192.168.0.1(Pos1/0/0)s neighborsRouter ID: 2.2.2.2 Address: 192.168.0.2State: Full Mode:Nbr is Master Priority: 1 DR: None BDR: None MTU: 0 Dead timer due in 36 sec Retrans timer interval: 5 Neighbor is up for 00:15:04 Authentication Sequence: 0 Neighbors Area 0.0.0.1 interface 192.168.1.1(Pos2/0/0)s neighborsRouter ID: 3.3.3.3 Address: 192.168.1.2State: Full Mode:Nbr is Master Priority: 1 DR: None BDR: None MTU: 0 Dead timer due in 39 sec Retrans timer interval: 5 Neighbor is up for 00:07:32 Authentication Sequence: 0 # 显示RouterA的OSPF路由信息。RouterA display ospf routing OSPF Process 1 with Router ID 1.1.1.1 Routing Tables Routing for Network Destination Cost Type NextHop AdvRouter Area 172.16.1.0/24 2 Transit 192.168.1.2 3.3.3.3 0.0.0.1 172.17.1.0/24 3 Inter-area 192.168.0.2 2.2.2.2 0.0.0.0 192.168.0.0/24 1 Stub 192.168.0.1 1.1.1.1 0.0.0.0 192.168.1.0/24 1 Stub 192.168.1.1 1.1.1.1 0.0.0.1 192.168.2.0/24 2 Inter-area 192.168.0.2 2.2.2.2 0.0.0.0 Total Nets: 5 Intra Area: 3 Inter Area: 2 ASE: 0 NSSA: 0# 显示RouterA的LSDB。RouterA display ospf lsdb OSPF Process 1 with Router ID 1.1.1.1 Link State Database Area: 0.0.0.0 Type LinkState ID AdvRouter Age Len Sequence Metric Router 2.2.2.2 2.2.2.2 317 48 80000003 1 Router 1.1.1.1 1.1.1.1 316 48 80000002 1 Sum-Net 172.16.1.0 1.1.1.1 250 28 80000001 2 Sum-Net 172.17.1.0 2.2.2.2 203 28 80000001 2 Sum-Net 192.168.2.0 2.2.2.2 237 28 80000002 1 Sum-Net 192.168.1.0 1.1.1.1 295 28 80000002 1 Area: 0.0.0.1 Type LinkState ID AdvRouter Age Len Sequence Metric Router 5.5.5.5 5.5.5.5 214 36 80000004 1 Router 3.3.3.3 3.3.3.3 217 60 80000008 1 Router 1.1.1.1 1.1.1.1 289 48 80000002 1 Network 172.16.1.1 3.3.3.3 670 32 80000001 0 Sum-Net 172.17.1.0 1.1.1.1 202 28 80000001 3 Sum-Net 192.168.2.0 1.1.1.1 242 28 80000001 2 Sum-Net 192.168.0.0 1.1.1.1 300 28 80000001 1# 查看RouterD的路由表，并使用Ping进行测试连通性。RouterD display ospf routing OSPF Process 1 with Router ID 4.4.4.4 Routing Tables Routing for Network Destination Cost Type NextHop AdvRouter Area 172.16.1.0/24 4 Inter-area 192.168.2.1 2.2.2.2 0.0.0.2 172.17.1.0/24 1 Transit 172.17.1.1 4.4.4.4 0.0.0.2 192.168.0.0/24 2 Inter-area 192.168.2.1 2.2.2.2 0.0.0.2 192.168.1.0/24 3 Inter-area 192.168.2.1 2.2.2.2 0.0.0.2 192.168.2.0/24 1 Stub 192.168.2.2 4.4.4.4 0.0.0.2 Total Nets: 5 Intra Area: 2 Inter Area: 3 ASE: 0 NSSA: 0RouterD ping 172.16.1.1 PING 172.16.1.1: 56 data bytes, press CTRL_C to break Reply from 172.16.1.1: bytes=56 Sequence=1 ttl=253 time=62 ms Reply from 172.16.1.1: bytes=56 Sequence=2 ttl=253 time=16 ms Reply from 172.16.1.1: bytes=56 Sequence=3 ttl=253 time=62 ms Reply from 172.16.1.1: bytes=56 Sequence=4 ttl=253 time=94 ms Reply from 172.16.1.1: bytes=56 Sequence=5 ttl=253 time=63 ms -
