+shall be trusted more than the others because they have the knowledge about
+which address space is allocated to each ASN, other databases lack this
+knowledge and can (and actually do) contain some stale data: nobody but RIRs
+care to remove outdated route-objects when address space is revoked from one
+ASN and allocated to another. In order to keep their filters both compact and
+current, *bgpq4 users* are encouraged to use one of two method to limit
+database sources to only ones they trust.
+
+One option is to use the '-S' flag. This limits all queries to a specific data
+source. For example, the following command tells IIRd to only use data from
+the RIPE RIR DB to build the prefix list for the AS-SET:
+
+	$./bgpq4 -S RIPE AS-VOSTRON
+	no ip prefix-list NN
+	ip prefix-list NN permit 89.21.224.0/19
+	ip prefix-list NN permit 134.0.64.0/21
+
+Be aware though, than an AS-SET may contain members from other data sources.
+In this case IRRd won't respond to the bgpq4 query will all the prefixes in the
+AS-SET tree. Make sure to use the '-S' flag with all the data sources required
+for the AS-SET being expanded:
+
+	$./bgpq4 -S RIPE,ARIN AS-VOSTRON
+	no ip prefix-list NN
+	ip prefix-list NN permit 89.21.224.0/19
+	ip prefix-list NN permit 134.0.64.0/21
+	ip prefix-list NN permit 208.86.232.0/24
+	ip prefix-list NN permit 208.86.233.0/24
+	ip prefix-list NN permit 208.86.234.0/24
+	ip prefix-list NN permit 208.86.235.0/24
+
+The other option is to specify a source for an AS-SET or Route Set using the
+"::" notation. When bgpq4 detects this, it will look for "::" in the specified
+AS-SET or RS on the CLI, and in all members of the AS-SET/RS, and for each
+member with a data source specified in "::" format, it will set the IRRd data
+source to the given value, query the AS-SET/RS, then reset the data sources back
+ to the default list for the next object in the tree.
+
+	$./bgpq4 RIPE::AS-VOSTRON
+	no ip prefix-list NN
+	ip prefix-list NN permit 89.21.224.0/19
+	ip prefix-list NN permit 134.0.64.0/21
+	ip prefix-list NN permit 208.86.232.0/22
+	ip prefix-list NN permit 208.86.232.0/24
+	ip prefix-list NN permit 208.86.233.0/24
+	ip prefix-list NN permit 208.86.234.0/24
+	ip prefix-list NN permit 208.86.235.0/24
+
+In comparison to the '-S' flag, this method return all the prefixes under the
+AS-SET, but the root of the tree "AS-VOSTRON" was queries from RIPE only. None
+of the member objects used the "::" notation so they were queries from the
+default source list (which is all sources).
+
 
 General recommendations:
 
 Use minimal set of RIR databases (only those in which you and your
 customers have registered route-objects).
 
-Avoid using ARIN-NONAUTH and RIPE-NONAUTH as trusted source: these records
+Avoid using ARIN-NONAUTH and RIPE-NONAUTH as trusted sources: these records
