OSPF on X440 Edge Core

Hi.
Can I make work OSPF in a X440 network?
I have 3 X440, two on remote locations, and one in HQ. I have configured the OSPF by this way:

Switch "80":
configure ospf routerid 0.0.0.80
create ospf area 0.0.0.1
configure ospf add vlan VLAN_A area 0.0.0.1
configure ospf add vlan VLAN_B area 0.0.0.1
enable ospf

Switch "81":
configure ospf routerid 0.0.0.81
create ospf area 0.0.0.1
configure ospf add vlan VLAN_B area 0.0.0.1
configure ospf add vlan VLAN_C area 0.0.0.1
enable ospf

Switch "82":
configure ospf routerid 0.0.0.82
create ospf area 0.0.0.1
configure ospf add vlan VLAN_A area 0.0.0.1
configure ospf add vlan VLAN_C area 0.0.0.1
enable ospf

And if I check the ospf in the interfaces:

SWITCH80.25 # show ospf interfaces VLAN IP Address AREA ID Flags Cost State Neighbors
VLAN_A 10.0.1.1 /24 0.0.0.1 -rif--- 4/A ODR 1
VLAN_B 10.0.2.1 /24 0.0.0.1 -rif--- 4/A ODR 1

And the same in the switches 81, and 82.
What is the ODR? Why are not working the OSPF?

Edgar,

You can use the X440 for edge OSPF but since they cannot be used with a core license they can never be a DR. Thus with no DR there is not a designated OSPF router to hold the database. You have to have another device that holds a core license (in Extreme world) or another router that can act as a DR. Let me know if you have a question!
