步骤七使用OSPF配置路由
1.配置OSPF
R1
[R1]ospf 1 router-id 1.1.1.1
[R1-ospf-1]area 0
[R1-ospf-1-area-0.0.0.0]network 192.168.1.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[R1-ospf-1-area-0.0.0.0]network 20.1.1.0 0.0.0.255
R2
[R2]ospf 1 router-id 2.2.2.2
[R2-ospf-1]area 0
[R2-ospf-1-area-0.0.0.0]network 10.1.1.0 0.0.0.255
[R2-ospf-1-area-0.0.0.0]network 192.168.2.0 0.0.0.255
R3
[R3]ospf 1 router-id 3.3.3.3
[R3-ospf-1]area 0
[R3-ospf-1-area-0.0.0.0]network 192.168.3.0 0.0.0.255

[R5]ospf 1 router-id 5.5.5.5
[R5-ospf-1]area 0
[R5-ospf-1-area-0.0.0.0]network 192.168.5.0 0.0.0.255
[R5-ospf-1-area-0.0.0.0]network 20.1.1.0 0.0.0.255
R6
[R6]ospf 1 router-id 6.6.6.6
[R6-ospf-1]area 0
[R6-ospf-1-area-0.0.0.0]network 20.1.1.0 0.0.0.255
[R6-ospf-1-area-0.0.0.0]network 192.168.6.0 0.0.0.255
2.修改接口网络类型 查看接口网络类型方法 display ospf interface Tunnel 0/0/0 修改接口网络类型方法 进入对应接口(隧道接口)后 ospf network-type ~类型~ 3.打开伪广播 进入对应接口(中心站点隧道)后 nhrp entry multicast dynamic 4.强制规定DR 将同时存在于俩个MGRE网络内的路由器设置为DR 更改一些接口优先级以达让某些路由器接口不参与选举 进入对应接口(隧道接口)后 ospf dr-priority 0 步骤八检测
