Hi Chris, That will work, however I'm wondering what the point of " bgp-input-remote-as 64496" is when you're applying the filter to that bgp peer connection anyway? What scenario would arise where that would actually filter anything, unless you accidentally applied that filter to another connection? My filter from IX Route servers in simply: jump validate_route; (this filters bogons, rejects our prefixes, validates rpki, adds pref-src IP and returns) set bgp-local-pref 150; accept; Regards, Dirk Bermingham -----Original Message----- From: Public <public-bounces@talk.mikrotik.com.au> On Behalf Of Christopher Hawker via Public Sent: Monday, November 6, 2023 10:10 AM To: public@talk.mikrotik.com.au Cc: Christopher Hawker <chris@thesysadmin.dev> Subject: [MT-AU Public] Sanity Check on Route Filters Hey all, Just looking to get a sanity check done on a route filter. If an AS is receiving routes from an IX route server, will this allow routes from the RS to be received? I'm confident it will, however just looking for validation before we test it. /routing filter rule add chain=AS64496-V4-IN disabled=no rule="if ( bgp-input-remote-as 64496) { set bgp-local-pref 200; accept }" Regards, Christopher Hawker _______________________________________________ Public mailing list Public@talk.mikrotik.com.au http://talk.mikrotik.com.au/mailman/listinfo/public_talk.mikrotik.com.au
