RFC8950 with Juniper issue

by Marian Rychtecky

Hi all, short info - we have two ASNs running JunOS 19.4. Even Juniper officially supports RFC 8950 from 17.3R1 on MX and 20.1R1 on QFX (https://lists.ix-f.net/hyperkitty/list/rfc8950@lists.euro-ix.net/message/GV…) those networks are struggling to get RFC8950 enabled. Juniper announces "enhanced next-hop" capability, however receiving an IPv4 prefix with two next-hops (local-link and global) will tear down the BGP session. The logged message says "bad nhop len: 32 for afi 1, safi 1" - clearly not expecting two next-hops. I do not have any Juniper to test with and this sounds like an incompatibility with RFC 8950 where both next-hops are expected as per: What are your thoughts on a problem like this?

meeting postponed to Jan 23rd

by Aleksi Suhonen

Hello, My co-chair, Andre, is down with flu, and our zoom host, Bijal, is on leave, so today does not seem to be an auspicious time to have an RFC8950 working group meeting. Unless somebody responds with a better idea, I'm moving the meeting by a week to Tuesday January 23rd starting at 13:00 UTC. Bijal will send a new meeting invite complete with the Zoom link once she has a chance. I hope. Until we meet again, -- +358 44 9756548 / http://www.trex.fi/ Aleksi Suhonen / TREX Regional Exchanges Oy You say "potato", I say "closest-exit."

FW: Junos/Juniper Support for RFC 8950

by Moyaze Shivji

Hi Guys As agreed I would share what the LINX’s Juniper SE shared with me with regards to RFC8950. Hope this is useful info. Mo Hi Mo, Hope you’re well. We support RFC5549 (predecessor to RFC8950) on MX since 17.3R1. Other platforms like QFX had support added later as per below: https://apps.juniper.net/feature-explorer/feature-info.html?fKey=7931&fn=Re… Below are some PRs that affected RFC8950 compliance: PR1649332<https://prsearch.juniper.net/problemreport/PR1649332> : RFC 8950 Extended Nexthop Encoding Capability conformance issue PR1716946<https://prsearch.juniper.net/problemreport/PR1716946> : BGP connection doesn't establish when it is configured with rfc8950-compliant under logical-systems on all Junos and Junos OS Evolved platforms From the last PR, the fixes are available in: 22.4R2 22.4R3 23.1R2 23.2R1 23.3R1 Reference documentation: https://www.juniper.net/documentation/us/en/software/junos/bgp/topics/topic… For point to point BGP peering, the dynamic tunnels described in above doc are not required. I tested on 23.1R2 and below is my simple topology and sample config: LAN01(2.2.2.0/24) ------- ge-0/0/2 - R1 (AS65001) - ge-0/0/1---- v6 Peering ---- ge-0/0/1 R2 (AS65002) ge-0/0/2 ------- LAN02 (1.1.1.0/24) root> show configuration protocols bgp group TEST { type external; local-address 2001:db8::2; family inet { unicast { extended-nexthop; } } export EXPORT-BGP; peer-as 65001; neighbor 2001:db8::1; } rfc8950-compliant; root> show configuration interfaces ge-0/0/1 unit 0 { family inet; family inet6 { address 2001:db8::2/64; } } root> show route table inet.0 1.1.1.0/24 inet.0: 6 destinations, 6 routes (6 active, 0 holddown, 0 hidden) + = Active Route, - = Last Active, * = Both 1.1.1.0/24 *[BGP/170] 14:18:30, localpref 100 AS path: 65001 I, validation-state: unverified > to 2001:db8::1 via ge-0/0/1.0 Please let me know if you would like to have a quick call to go through.
