[ixpmanager] Route limit for RS conf generation

Thanks. 

Where can I find the script that actually creates the RS config? I’ll see if I can modify it to behave the way I want it to and let you know if I succeed so that you can use it if you want to.

Also, I’ve run into another issue that you might be able to help with:

A customer has a route object for /32 and then announces a /34 within that range, but they haven’t created a route object for it. How do I configure BIRD to allow those subprefixes? My current/previous setup did this, but I haven’t been able to figure out what part of the config that creates this diff in behaviour.

    Yeah, so this is something that needs a bit of a clean up and a v4/v6
    split. Right now, you can put max prefixes in two places:
    
    1) under the customer's overall profile which you've found above
    2) on a per (vlan) interface basis.
    
    This is historical crud more than anything else but the logic is:
    
    if vlan interface max exists and is > 0 , use it; else use the customer
    details setting.

    If you have no prefixes for a customer and don't want to apply strict
    prefix checking on your route servers (not advisable) then you can
    uncheck the 'Apply IRRDB Filtering' under vlan interface also. Again,
    this is not broken out for v4/v6 when it should be.
    
    Note that the default action when IRRDB Filtering is enabled with no
    prefixes found is to reject all.
    
    I wouldn't advocate changing the code as it'll make upgrades difficult
    but it can easily be done if you like. Perhaps open a feature request to
    add a --quiet option to mute these?
