Dear all, I'm quite new to RtConfig, I would like to know how I can generate import filters both using prefix lists and as-path lists. Playing around with RIPE test database I got this: if I specify an import policy in such a way: import: from ASx accept ASy (having a route object for ASy), then "@RtConfig import ASx <ip-addr-x> ASy <ip-addr-y>" gives me back a filter based on prefix lists. Otherwise, if I specify an import policy (or similar): import: from ASx accept <^ASy+$> then I get back a filter based on an as-path. So the main difference seems to reside in the way the aut-num object is written: using simple AS names gives prefix list filters, using regular expressions on AS names gives as-path based filters, am I right ? Is there a way to combine both things to obtain both types of filters for the same peering relationship ? Thank you in advance and best regards, Francesco Ferreri -- ----------------------------------------- Francesco Ferreri NaMeX - Nautilus Mediterranean Exchange Via dei Tizii 6b, 00185 - Roma Tel. +39-0644486.302 E-mail: f.ferreri@namex.it WWW http://www.namex.it -----------------------------------------
