OSPF外部路由实验-基础篇
//upload-images.jianshu.io/upload_images/24325874-46242f6ded1386d3
实验说明:R1通过静态路由访问公司B的服务器网段192.168.1.0/24,由于公司A也需要访问公司B的服务器，所以需要在R1上将该静态路由引入OSPF，使得公司A也能访问服务器.
详细配置:1.公司A网络配置接口ip并宣告进相应ospf,保证PC1和PC2之间连通R1interface g0/0/0ip add 10.1.12.1 24interface g0/0/1ip add 10.1.13.1 24interface g0/0/2ip add 10.1.15.1 24ospf 1 router-id 1.1.1.1area 0network 10.1.12.1 0.0.0.0area 2network 10.1.13.1 0.0.0.0R2interface g0/0/1ip add 10.1.24.2 24interface g0/0/0ip add 10.1.12.2 24ospf 1 router-id 2.2.2.2area 0network 10.1.12.2 0.0.0.0area 1network 10.1.24.2 0.0.0.0R3interface g0/0/0ip add 10.1.13.3 24interface g0/0/1ip add 10.1.2.254 24ospf 1 router-id 3.3.3.3area 2network 10.1.13.3 0.0.0.0network 10.1.2.254 0.0.0.0R4interface g0/0/0ip add 10.1.24.4 24interface g0/0/1ip add 10.1.1.254 24ospf 1 router-id 4.4.4.4area 1network 10.1.24.4 0.0.0.0network 10.1.1.254 0.0.0.0PC1

PC2
//upload-images.jianshu.io/upload_images/24325874-5131ba934676621c
检查现象:PC1可以ping通PC2

2.公司B相关配置(1) 相关接口ip配置R5interface g0/0/0ip add 10.1.15.5 24interface g0/0/1ip add 192.168.1.254 24Server
//upload-images.jianshu.io/upload_images/24325874-577441f4d094c10a
(2) R5做为出口路由器配置默认路由R5ip route-static 0.0.0.0 0 10.1.15.1检查现象:display ip routing-table
//upload-images.jianshu.io/upload_images/24325874-448d78a753f0920d
3.保证公司A能够访问公司B的server(1) R1上配置一条静态指向ServerR1ip route-static 192.168.1.0 24 10.1.15.5检查现象:R1-ping 192.168.1.1
//upload-images.jianshu.io/upload_images/24325874-b22973bd90a99e46
(2) R1上将静态路由引入进ospfR1ospf 1import-route static检查现象:R1,R2,R3,R4 display ospf lsdb都能看见5类外部LSA
//upload-images.jianshu.io/upload_images/24325874-f958d1383b46061f
display ospf LSDB ase 192.168.1.0
//upload-images.jianshu.io/upload_images/24325874-f7a3b4ae6030e322
R4上还能看到R2通告给它的4类LSA
//upload-images.jianshu.io/upload_images/24325874-f0cbb4ab8a4bda5d
PC2 ping 192.168.1.1
