The RPLS ‘via’ attributes IETF89, London RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Who am I? Job Snijders Network AS Hibernia Networks Founder of NLNOG RING Hobbies: IP Routing, LISP, MPLS, IPv6, RPSL Shoe size: 45/EU RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Problem statement Today there is not really a good way to instruct a Route Server to whom they should announce your prefixes. RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Problem statement refined You can ONLY describe routing policy related to directly adjacent networks. RPLS-VIA - IETF89 - Job Snijders Hibernia Networks Import: Export: Here is nothing

Current methods BGP Communities (issue: too small) RPSL (but no way to describe indirect) BGP Communities in RPSL Web interface (out of band, not universal) Mapping systems (map 32bit AS to 16bit value) RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Proposal: draft-snijders-rpsl-via aut-num: AS5580 import-via: AS6777 from AS action pref = 2; accept AS-SNIJDERS import-via: AS6777 from AS5580:AS-CUSTOMERS accept NOT ANY export-via: AS6777 to AS action community.={5580:40}; announce AS-ATRATO export-via: AS5580:AS-ROUTESERVERS to AS5580:AS-CUSTOMERS announce NOT ANY RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Advantages Only IRRs and IXP operators need to upgrade – Some IXP operators have already pledged! No BGP / router upgrades needed Immediate support for 32 bit ASNs 95% of people just want any to any (don’t need to update their autnum for that) Helps with Route Server Path Hiding RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Current implementation status OK: RADB / IRRd (since 3.0.7) OK: RIPE Whois Server (since 1.71) NOT YET OK: APNIC (runs APNICv1r0) – (but they sort of committed to merge my code) Unknown: ARIN, ALTDB (IRRdb fork), JPNIC (IRRd fork), LACNIC, AfriNIC RPLS-VIA - IETF89 - Job Snijders Hibernia Networks

Questions? Should this be WG document or Individual submission? Standards track or something else? There is running code, but is there consensus? RPLS-VIA - IETF89 - Job Snijders Hibernia Networks
