Gops,

I had the same problem in 3640 old 12.4 release before. It is an IOS
bug. I resolved it by downloading newer IOS 12.4 release.

Which IOS release do you have?

        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 <http://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 <http://2.2.2.2/>
