Dear Collins,
Sorry, there is a typing mistake.
Final config is config R5 as ip ospf network point-to-multipoint
non-broadcast + neighbor, R2 & R6 still keep ip ospf network point-to-point.
and the result is that the ospf neighbor on R6 will get flapping. When the
neighbor form with R2, it will disconnect with R5. few second later,
disconnect with R2 and connect to R5.
Regards,
Howard

How about configuring R5 as "ip ospf network point-to-multipoint
non-broadcast"? This should work with the hub a normal "ip ospf network
point-to-multipoint".

Dear all,
In the IPExpert LAB 39, OSPF part. There is a hub & spoke between
R2,R5,R6 and R6 is the hub. The task request to config "ip ospf network
point-to-point" between R2 & R6 and config R5 to not broadcast ospf packet.
The final confi is to config ip ospf network point-to-multipoint
I'm ok with
the R5 config, but this will make the ospf neighbor flapping because R6 is
the
point to point ospf interface. the neighbor won't be stable and I supose
it's
a problem before I read the final config.
I'm really doubt that it won't
acceable in the real lab, isn't it?
