Hi experts,
I am facing the issue with OSPF R2 is connected to R3 with Ethernet(Broadcast Mode) and with 2 serial links to R1 (NBMA Mode) i am not allowed to enter neighbor command under the router ospf 1
when i give this command :-
router ospf 1 neighbor 2.2.12.1
it gives the error —>
“OSPF: Neighbor command is allowed only on NBMA and point-to-multipoint networks” “OSPF: Neighbor command is allowed only on NBMA and point-to-multipoint networks”
is this the default behavior or i am missing something here????
It takes the neighbor command before i give the ethernet link network command. but when i reload it…it again generates the above error message and neighbor commands are automatically removed from the Router ospf configuration…following is the output after i reloaded the Router and it disregarded the neighbor commands…..
My question is “does the router not take the neighbor command for NBMA under router ospf, when it has ethernet link also for ospf, on the same router???” I have the following config :—
router ospf 1 router-id 2.2.2.2 log-adjacency-changes network 2.2.2.2 0.0.0.0 area 2 network 2.2.12.2 0.0.0.0 area 2 network 2.2.12.6 0.0.0.0 area 2
neighbor 2.2.12.1
