This is from IE v4.1 Lab 1 Task 3.2
Task states to ensure host devices running OSPF on vlan 45 cannot
intercept communication between R4 and R5.
Solution states to configure ethernets as ospf type non-broadcast and
configure neighbor statements. At first OSPF would not take the
neighbor statement and came back with "OSPF: Neighbor command is
allowed only on NBMA and point-to-multipoint networks"
Rack4R4(config)#int fa0/0
Rack4R4(config-if)#ip ospf network non-broadcast
Rack4R4(config-if)#router ospf 1
Rack4R4(config-router)#
Rack4R4(config-router)#network 183.4.45.4 0.0.0.0 area 45
Rack4R4(config-router)#neighbor 183.4.45.5
OSPF: Neighbor command is allowed only on NBMA and point-to-multipoint networks
Rack4R4(config-router)#neighbor 183.4.45.5
OSPF: Neighbor command is allowed only on NBMA and point-to-multipoint networks
Rack4R4(config-router)#
But once I deleted the OSPF config and re-added, it accepted the
neighbor statement:
Rack4R4(config-if)#router ospf 1
Rack4R4(config-router)#net
Rack4R4(config-router)#network 183.4.45.4 0.0.0.0 area 45
Rack4R4(config-router)#nei
Rack4R4(config-router)#neighbor 183.4.45.5
Rack4R4#show ip ospf nei
Neighbor ID Pri State Dead Time Address Interface
150.4.5.5 1 FULL/BDR 00:01:31 183.4.45.5
FastEthernet0/0
Anyone come across this before?
