Re: Theorical question about cyclic dependency in IRR filtering

Hi Anurag, Circular dependencies definitely are a thing to keep in mind when designing IRR and RPKI pipelines! In the case of IRR: It is quite rare to query the RIR IRR services directly. Instead, the common practise is that utilities such as bgpq3, peval, and bgpq4 query “IRRd”

Hello everyone, While discussing IRR on some groups recently, I was thinking if there can be (and if there is) cycling dependency in filtering where IRR (run by whoever APNIC, RIPE, RADB etc) uses some upstream and accepts only routes with existing & valid route object. So hypothetical case
