Aamir,

do you have some virtual-link configuration under ospf?

Once (when I try to lab it IEWB lab 1 at my poor home lab) I noticed that if
I enter virtual link config first, and then neighbor statement, I got the
same output (OSPF: Neighbor command is allowed only on NBMA and
point-to-multipoint networks).

But when I entered these commands in reverse order (first neighbor, than
virtual link), then everything was ok.

HTH,
Srdja

HI there ppl,

I have a hub and spoke environment like this R2-------R5-------R3,

R5 is the hub with s0/0.235 multipoint interface meaning by default NBMA
mode, which requires neighbor command on R5 but when i reboot R5 i get this
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

and the neighbor command is no longer there in OSPF of R5, what is happening
here?? i have given ip ospf priority 0 on R2 and R3 to R5 as DR

Thanks
Aamir
