Hello bugs@,
I ran into an odd issue when adding a new vlan interface (1916) into a
running ospfd. While reloading ospfd, ospfd didn't pick up the new vlan
interface and returns an "unnumbered interface" error and citing the syntax
of ospfd.conf is incorrect.
When I renamed the vlan interface name to a different vlan interface, ospfd
reloads fine while the content of the new vlan interface is identical. So
it seems to be related to the vlan interface naming?
I have reproduced this on a test machine running openbsd 7.2 release, below
is the exact order to reproduce it. I have tested this on a system using
ixl and em interfaces, the results are similar.
This issue only appears when reloading ospfd, when restarting ospfd
completely using rcctl, the vlan1916 interface is working as expected.

### Fix by renaming the hostname.vlan1916 interface to hostname.vlan1000
## uncommenting vlan1916 from previous attempt
