Hello,
Are Point-to-Point and Point-to-Multipoint the only compatible pair of
Ospf Network Types (besides a type to itself)?
I have tested this in a hub & spoke topology, the hub has 2
point-to-point sub-interfaces (by "serial 0.1 point-to-point" & "serial
0.2 point-to-point", and when I creates the point-to-multipoint spoke
by "ip ospf network point-to-multipoint", everything is working as
expected.
However, leaving the hub the same, if I create the point-to-multipoint
spoke by "interface serial 0.1 multipoint" command rather than using
"ip ospf network point-to-multipoint" command, the OSPF adjacency would
form, but never exchange tables.
In both cases, I have set the Hello Interval at the hub's
point-to-point sub-interface to match the spokes by "ip ospf
hello-interval 30".
Kind Regards,
Hunt Lee
