Hi Jakob, but the as-set only checks the origin AS in the announcement, it doesn't lookup the prefix <-> as relation from RADB/RIPE/Whatever, as i understand it correctly! Or is there some lookup mechanism as Ytti/Mark mentioned? regards, tim On Sun, Aug 15, 2021 at 01:46:40AM +0000, Jakob Heitz (jheitz) via NANOG wrote:
Ytti, We have introduced the scalable as-set into the XR route policy language. as-path-set does not scale well with 1000's of ASNs. Now, you don't need to expand AS-SET into prefix-set, just enter it directly. Example: as-set test 2914, 3356, end-set ! route-policy sample if as-path originates-from test then pass endif end-policy If this does not meet your needs and you need improvements, let me know. Kind Regards, Jakob. ------------------------------------------------------------- Date: Mon, 9 Aug 2021 19:10:23 +0300 From: Saku Ytti <saku () ytti fi> We just recently learned of a IOS-XR prefix-set limit of 300001 when a particular customer AS-SET expanded to a higher number of prefixes. -- ++ytti
