Hi,

I dont know if there is any Service Provider in this list that uses
Intra-AS solution in a production network but I would like to know what
are the techniques used to filter vpn preffix in and out the AS. I know
that exists ORF and (now) regular expression for RT but it can become low
controlable (ORF solution) or RT provision too complex. Is any SP have
this kind of issues? Also what can I do if for example, a have more one
intra-as session to the same as provider and I want to control the
advertisement of the preffix in each session? By this time the way that I
know is to filter based in RT or normal community. Any more ideia? 

Thx,
Marcelo.
