RE: OSPF neighbor on non-broadcast OSPF network type

I have not tested this scenario, but perhaps you had it non-broadcast on one
side and broadcast on another at first, then through the course of your
experimentation changed them both to non-broadcast and one side still had
knowledge of the other neighbor from the previous contact or something
weird...who knows. The important thing here is that you truly understand
every possible network type matchup and all the possible timers as well as
how to get them up and running.

No problem joe ...I may be fat fingered but I was sure when I saw it and
just moved on to different topology as it was not the concern during that
time and meantime posted the question to u all .
 
Thanks

I'd really have to see the configurations to believe that one : ) No
offense, but non-broadcast on both sides with no neighbor statement just
simply won't work as far as I know.

Hi Joe,
 
  Both sides were non-broadcast and later me changed the topology to
broadcast on both sides to do some other scenario..I am trying to erase the
config and try to recreate the same topology to see whether it comes back .
 
Thanks

Generally you do need it, but without further information it is really
difficult for us to tell you exactly. We need to know the network type on
the other side as well.

Subject: OSPF neighbor on non-broadcast OSPF network type

Hi All,

  I ran OSPF on an non-broadcast OSPF network type between R1 and R2 and
saw the neighbor came up without configuring explicitly "neighbor " command
under the OSPF process.I was assuming the neighbor command is
required.Kindly let me know on this and also if missed some basic on it.

Thanks
