[ixpmanager] AS-SET Is not Working

[Shahab Vahabzadeh]

Dear Nick,
You are right but what is your idea about this prefix: 185.141.213.0/24 ?
There is a route object in ripe with AS43754 and this AS belongs to the
customer himself.
But again it's filter with two tag: Prefix Filtered, Origin AS Filtered
Thanks
