Yup, I got it!

It appears there is a bug in the RIPE NCC RPKI Cache Validator, or a
visibility issue in the RIPE RIS collection mechanism. I'd suspect the
former, as RIPE RIS itself receives a fair amount of scrutiny compared
to the "BGP Preview" feature in the validator.

The full story is this:

    $ bgpctl show rib 194.45.182.0/23 all
    flags: * = Valid, > = Selected, I = via IBGP, A = Announced,
           S = Stale, E = Error
    origin validation state: N = not-found, V = valid, ! = invalid
    origin: i = IGP, e = EGP, ? = Incomplete

    flags ovs destination          gateway          lpref   med aspath origin
    I*>     V 194.45.182.0/23      165.254.255.1      100  1001 2914 286 i
    I*>     ! 194.45.182.0/24      165.254.255.1      100  1001 2914 286 2858 { 517 } i
    I*>     ! 194.45.183.0/24      165.254.255.1      100  1001 2914 286 2858 { 517 12469 } i

The "BGP Preview" is only showing the /23, but the issue at hand is
expressed in the two /24s covered by the /23.

Kind regards,

Job
