RIS raw data

Thu Jan 19 11:24:04 UTC 2012

Hi all, 

I am working on getting a better grasp on what data we
have in the RIS project from RIPE. 
To this end, I am checking the
export policies of the ASes peering with RIPE AS12654 at different
IXPs.
I am wondering if anybody knows what these ASes actually
announce to the RIPE repositories? Do they dump their entire routing
tables (including their internal routes) ?  
In some cases I saw
the export policy ANNOUNCE ANY, is this consistent with a particular AS
behaving like the RIPE AS was its customer? 
Another type of export
policy is for example 'to AS12654:  ANNOUNCE AS "YYY"
'(where  "YYY" is any AS peering with RIPE in the RIS
project). 
How is this policy different from the previous one from
the point of view of the routing feed the RIPE repository receives? 

Thank you for your help! 

Best regards, 
Andra
