[ixpmanager] IRR updating issue with BGPQ3

[Barry O'Donovan (INEX)]

Hi Paul,

we can't remove the -S flag as IXP administrators would then have no 
control over that IRR databases are being queried. Some databases 
contain good quality data and others not so much.

However, you can control this yourself via the IRRDB Configuration 
option in the left hand side admin menu and then setting the is each 
customer's profile as appropriate. E.g. some networks are RIPE only, 
others may be global and require multiple sources.

IXP Manager installs a bunch of options by default:

bgpq3 also has some useful notes on this:
