Since it was a quiet day in early April, Ben and I whipped up something
to generate config in industry standard format to mimic the RFC 6811
RPKI based BGP Origin Validation procedure. It uses the 'route-map'
configuration construct found in some older BGP implementations.

We didn't test this in production, but I reckon you can upload the
generated output into the router's 'running-config' using a hourly
crontab, TFTP, RANCID, and expect(1). Here is an example config to
copy+paste. If we don't hear back from you we'll assume success.

After applying the above you can reference 'rpki-ov' at each of your
EBGP peers as ingress policy: "neighbor x.x.x.x route-map rpki-ov in".

Be careful though, performance may not be as good as a native RPKI OV
implementation!

Cheers,

Job & Ben
