Ive got some questions while playing with filters, but couldn't figure the most important thing... anyone could help me please?
Consider the following scenario:
AS1<---BGP--->AS2<---BGP--->AS3
AS3 is actually a traffic exchange point. AS2 already receive routes from AS3 without its ASN in AS_PATH. How to advertise these routes to AS1 without AS2 number? Also, Ive put a "Route TAG" on routes from AS3, but noticed that AS1 peer just received two routes less than that peer inside AS2 to AS3. Guess its not like that the correct way to do this, right?
Please, thank you in advance.
