08b81f7d19 Parse 'SOURCE::' to only use a specific source for an AS-SET or Route Set
This extension allows operators to specify what IRR source to use when expanding an AS-SET.

For example: `bgpq4 RIPE::AS15562:AS-SNIJDERS`

The notation is also used in databases like PeeringDB.

# NOTES ON SOURCES
By default *bgpq4* trusts data from all databases mirrored into NTT's IRR service.
Unfortunately, not all these databases are equal in how much can we trust their
data.
RIR maintained databases (AFRINIC, ARIN, APNIC, LACNIC and RIPE)
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care to remove outdated route-objects when address space is revoked from one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 sources: these records
were created in database but for address space allocated to different RIR,
so the NONAUTH databases have no chance to confirm validity of this route
object.

.Sh NOTES ON SOURCES
By default
.Em bgpq4
trusts data from all the databases mirrored into NTT's IRR service.
Unfortunately, not all these databases are equal in how much we can
trust their data.
RIR maintained databases (AFRINIC, ARIN, APNIC, LACNIC and RIPE)
shall be trusted more than the others because they have the
knowledge about who the rightful holders of resources are, while
other databases lack this knowledge and can (and, actually do) contain
stale data: no one but the RIRs care to remove outdated route-objects
when address space is de-allocated or transferred.
In order to keep their filters both compact and actual,
.Em bgpq4 users
are encouraged to use '-S' flag to limit database sources to only
the ones they trust.
.Pp
General recommendations:
.Pp
Use a minimal set of RIR databases (only those in which you and your
customers have registered route-objects).
.Pp
Avoid using ARIN-NONAUTH and RIPE-NONAUTH as trusted sources: these records
were created in the database, but for address space allocated to different RIRs,
so the NONAUTH databases have no chance to confirm validity of the route
objects they contain.
