NBMA非广播模式下配置OSPF

 

routerA:

interface Loopback0
 ip address 1.1.1.1 255.255.255.0
!
interface Serial0/1
 ip address 192.1.1.1 255.255.255.0
 encapsulation frame-relay
 serial restart-delay 0
!
router ospf 10
 log-adjacency-changes
 network 1.1.1.0 0.0.0.255 area 0
 network 192.1.1.0 0.0.0.255 area 0
 neighbor 192.1.1.2
 neighbor 192.1.1.3

routerB：

interface Loopback0
 ip address 2.2.2.2 255.255.255.0
!
interface Serial0/2
 ip address 192.1.1.2 255.255.255.0
 encapsulation frame-relay
 ip ospf priority 0
 serial restart-delay 0
 frame-relay map ip 192.1.1.1 201 broadcast
 frame-relay map ip 192.1.1.3 201 broadcast
!
router ospf 10
 log-adjacency-changes
 network 2.2.2.0 0.0.0.255 area 0
 network 192.1.1.0 0.0.0.255 area 0

routerC：

interface Loopback0
 ip address 3.3.3.3 255.255.255.0
!
interface Serial0/3
 ip address 192.1.1.3 255.255.255.0
 encapsulation frame-relay
 ip ospf priority 0
 serial restart-delay 0
 frame-relay map ip 192.1.1.1 301 broadcast
 frame-relay map ip 192.1.1.2 301 broadcast
!
router ospf 10
 log-adjacency-changes
 network 3.3.3.0 0.0.0.255 area 0
 network 192.1.1.0 0.0.0.255 area 0

看一下邻居的关系，routerA为DR，B,C,为DROTHER

routerA#sh ip ospf neighbor

Neighbor ID     Pri   State           Dead Time   Address         Interface
2.2.2.2           0   FULL/DROTHER    00:01:53    192.1.1.2       Serial0/1
3.3.3.3           0   FULL/DROTHER    00:01:44    192.1.1.3       Serial0/1

看路由表，能够相互学到全部路由

routerA#sh ip route

     1.0.0.0/24 is subnetted, 1 subnets
