OSPF Notes – Network Types
Corrections are always welcome.
Broadcast : Think an Ethernet segement
DR/BDR? : Yes
Default hello interval : 10 sec
Neighbor config required? : No
Point-to-point : Physical point-to-point links, frame-relay point-to-point subifs
DR/BDR? : No
Default hello interval : 10 sec
Neighbor config required? : No
Nonbroadcast Multiaccess : Frame-relay multipoint or physical
DR/BDR? : Yes
Default hello interval : 30 sec
Neighbor config required? : Yes
Point-to-multipoint : Partial mesh networks like a frame-relay hub-and-spoke configuration
DR/BDR? : No
Default hello interval : 30 sec
Neighbor config required? : No
Point-to-multipoint nonbroadcast : Partial mesh networks like a frame-relay hub-and-spoke configuration but without the ability to broadcast
NOTE: I’m having trouble finding an example of this that doesn’t include changing routing preferences between two unequal paths.
DR/BDR? : No
Default hello interval : 30 sec
Neighbor config required? : Yes

Hey, loving the OSPF and EIGRP posts you are doing, I’m using them as knowledge tests to make sure I remember all the details.
Only thing I’ve noticed is a spelling mistake in the point-to-point description:
“frame-relate”
Keep them coming they are really useful!

More on the way, Tom!
