RPKI / roa_check() question - BIRD 2.0.2

[Jan Maria Matějka]

The bgp_path.last_nonaggregated attribute should help you. Don't have user manual right now here, writing from my phone, just trying to recall it from my memory.

Hello,

I have found this while doing RPKI validation:

net = 94.127.104.0/21
bgp_path = 48112 6830 174 13110 {30884 65004 65005}
BGP.aggregator: 10.253.27.1 AS13110 (don't know how to read this from a var)

roa_check(rpki4, net, bgp_path.last) returns ROA_INVALID because BIRD
thinks bgp_path.last = 0

There is a valid ROA for 94.127.104.0/21 and AS13110, so I guess the
validation should be done on the aggregator AS.

Could you tell me what is the corect way to handle this?

TIA,
Radu
