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.

Airheads Community I'm looking for a way to configure "passive-interface default" in router ospf and then configure "no ip ospf passive" on a few specific interfaces, including a View this on Airheads Community >

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

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?

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"))
