Will the filters be built off our aut-num object or just the as-set listed on PeeringDB?
I think they just use the as-set. Last night, I tested
the underlying command against someone who does not have an
aut-num, but does have route objects referencing their AS. Their
prefixes were found.
The underlying command is bgpq3. So if you really want to get low
level, install that somewhere and run bgpq3
AS_SET_NAME and bgpq3 -6
AS_SET_NAME. IXP Manager actually runs that with more
flags, but they aren't particular relevant (other than minimum
prefix length).
