ROV belongs on the input path, let's not ROV on the output towards
customers / route collectors.
Announcing bigger, ROV valid/unkown
There are 2 sides to the bgp conversation for any ASN, and then really 4 sides.
customer -> RAS -> peer (settlement-free)
peer(sfp) -> RAS -> customer
customer -> ras -> transit
transit -> ras -> customer
Depending on the RAS's capabilities or status in their journey to
'fully RAS',
Hello Job,
Thank you very much for your reply! I got that no AS can actually filter all
the invalids. Yet I was trying to figure out why we couldn't see reasonable
amount of withdrawals from AS6939 about invalid prefixes, as they explained how
they implement ROV
aside from technical reasons for an ROV-supporting AS (RAS) to announce
an ROV invalid prefix, there is an administrative one. the RAS's
customers *pay* RAS to announce the customers' prefixes. so RAS is
configured to propagate their customers' announcements without dropping
invalids.
