i have confederation AS 300 peer with AS100, AS 200.
AS 300 got 3 sub-as 65501,65502,65503. and i dont want AS 300 to be a
trasit as for AS100 and AS 200.
how should i filter it? initially i thougt using as-path filter to allow
only ^$ local as, then it proves only local sub-as routes will go out,
not allow the other two sub as go out of AS 300. then i thoght of using
community no-export. but then, if as100 or as 200 neighbor as want to
reach as 300, they cant as AS 100 or AS 200 wont advertise as 300's
routes.any idea? Sara
