deleted vlan/loopback still present

Take a look at this thread .  Feel free to revive the thread with a response if you need more information.

if you haven't done already (I'm guessing), go into admin -> manage nodes; find that node, click the + next to it to display all the interfaces, then check the ones that have been removed from the router.  click on the delete icon in upper right.

this should remove them from Orion.

If you've done this already, then see DanielleHs link.

Thanks njoylif that did the job , we are actually new in version 10.x.x (about 3 months) coming from version 9.5.1
