[lacnog] Fwd: BGP Experiment

[Edmundo Cázarez]

Hola,

Por lo pronto encontraron un “detalle” en FRR:

“


We've performed the first announcement in this experiment yesterday, and, despite the announcement being compliant with BGP standards, FRR routers reset their sessions upon receiving it.  Upon notice of the problem, we halted the experiments.  The FRR developers confirmed that this issue is specific to an unintended consequence of how FRR handles the attribute 0xFF (reserved for development) we used.  The FRR devs already merged a fix and notified users.

Hola Edmundo,

  Muy buena pregunta, en realidad no sé. Voy a ver si averiguo algo.



Gracias, saludos

NANOG,



We would like to inform you of an experiment to evaluate alternatives

for speeding up adoption of BGP route origin validation (research

paper with details [A]).



Our plan is to announce prefix 184.164.224.0/24 with a valid

standards-compliant unassigned BGP attribute from routers operated by

the PEERING testbed [B, C]. The attribute will have flags 0xe0

(optional transitive [rfc4271, S4.3]), type 0xff (reserved for

development), and size 0x20 (256bits).



Our collaborators recently ran an equivalent experiment with no

complaints or known issues [A], and so we do not anticipate any

arising. Back in 2010, an experiment using unassigned attributes by

RIPE and Duke University caused disruption in Internet routing due to

a bug in Cisco routers [D, CVE-2010-3035]. Since then, this and other

similar bugs have been patched [e.g., CVE-2013-6051], and new BGP

attributes have been assigned (BGPsec-path) and adopted (large

communities). We have successfully tested propagation of the

announcements on Cisco IOS-based routers running versions 12.2(33)SRA

and 15.3(1)S, Quagga 0.99.23.1 and 1.1.1, as well as BIRD 1.4.5 and

1.6.3.



We plan to announce 184.164.224.0/24 from 8 PEERING locations for a

predefined period of 15 minutes starting 14:30 GMT, from Monday to

Thursday, between the 7th and 22nd of January, 2019 (full schedule and

locations [E]). We will stop the experiment immediately in case any

issues arise.



Although we do not expect the experiment to cause disruption, we

welcome feedback on its safety and especially on how to make it safer.
