Dear Working Group, As discussed at RIPE 75 I want to forward a request by Job Snijders on GitHub: https://github.com/RIPE-NCC/whois/issues/410 Job is asking to add a “large_community" keyword to RPSL dictionary where applicable. And provides the following example: Suggestion: name the keyword large_community mp-export: afi ipv6.unicast to AS13105 announce AS-RCNET-V6 AND NOT large_community.contains(21414:0:570) export: to AS6777 action large_community .= { 6777:0:6777 }; announce AS-FORTHNET mp-import: afi ipv6.unicast from AS8631 msk-rs2.ripn.net action large_community={31376:0:2}; pref=100; accept AS-MSKROUTESERVER import: from AS35082 95.128.51.234 at 95.128.51.233 action pref=500; large_community.append(29527:0:35082,29527:0:60000,29527:0:61200,29527:0:61210); accept AS-VIBUS-LONDON filter-set: fltr-as21229-export descr: Filter for AS21229 exported prefixes filter: AS-TVNETWORK AND large_community(21229:0:1) From our end I do not see any issues implementing this on the server side, but I can’t speak to how this will be treated by scripts that may parse RPSL today. Please discuss. Kind regards, Tim Bruijnzeels Assistant Manager Software Engineering and Senior Technology Officer RIPE NCC
