Not aware of any known issue here ... but I did not check it in detail. I guess there is another thing missing/misconfigured which makes your Loopback not appear in the OSPF process.
Can you post the output of the following commands?
- show ip int brief | in lo
- show ip ospf inter
- show run int loopback <number>
- show run ospf (only interested in the "router ospf <process-id>" section)
- show ip route local | in lo
- show version
- show system inventory (sanitize serial numbers if you wish; interested in the switch model ("chassis"))
Regards,
Thomas

Subject: AOS-CX adding loopback to OSPF Area
As an update, I was able to add a loopback interface to an ospf area on a different CX switch. The AOS-CX version where it works is 10.1-.1030, and 10.09.1050 on the one that doesn't work. Is there a known issue?

I'm having a slight issue adding a loopback interface to an ospf area on our CX switches. On our older Aruba switches we can add the loopback to an area with the command ip ospf area 0 in the interface context. The reference document of the new aos-cx switches has a similar command executed in the interface context, ip ospf 1 area 0. When we run the command the loopback interface isn't added to the area, and we cant connect to it for management.

There is a thread relating to loopback being passive interfaces, but I'm not sure if that's relevant.

Can loopback interface be added to an ospf area on the CX switches?
