Chris,

Thanks for your reply. Could you explain this bit more. I am still confused
as the router refuse to accept this in ospf.
Are you saying that when a router has broadcast interfaces under ospf, it is
not possible to make router-id 0.0.0.0 on it.
please correct me if I misunderstand..
Is there a way that I can make a neighbour router-id appears as 0.0.0.0 from
sh ip ospf nei

Thanks

Emil

Hi,

Not explicitly. However, if you are faced with a frame-relay scenario where
the OSPF DR/BDR needs to have a router ID of 0.0.0.0 it is instructing you
to use "ip ospf net point-to-multipoint" command. Under these circumstances
no DR/BDR is elected so none exist. The OSPF routers register this by
setting their DR/BDR flags to 0.0.0.0

Hope this helps.

Regards,

Chris.
