[lacnog] Fwd: Calgary Internet Exchange (YYCIX) deploys world's first ASPA-filtering Route Servers

[Douglas Fischer]

¡Muy interesante!

Veo cosas buenas que se pueden hacer con este protocolo.
(Y muchos fat-fingers también. jajaja)

Pero, sinceramente, tengo la sensación de que estamos reinventando la
rueda. Lo mismo que siento por RPKI lo siento por ASPA.

El conjunto de características que ofrecen los protocolos IRR es aún más
superior que lo que se puede hacer con RPKI+ASPA.

Solo para ilustrar, la validación de origen que ofrece el IRR ha sido
desacreditada por:
  1- La omisión de muchas ASN que no hicieron los deberes.
  2- Acciones hipócritas de empresas que crearon registros proxy.
  2.1- Ser agravado por quienes mintieron descaradamente el AS de origen en
los Objetos de ROUTE[6].
  3- Bases de datos IRR que además eran hipócritas y no hacían ningún tipo
de control de registro proxy o similar, permitiendo crear un enorme legado
de objetos erróneos.

P.D.: Vale la pena alabar la base de IRR de LACNIC, que es casi 100% limpia
ya que se crea a partir de RPKI ROAa, y un cumplido mayor a TC(bgp.net.br)
que siempre ha tenido la regla de no permitir registros de Proxy y que el
100% de su base está vinculada a delegaciones realizadas por NIC.BR.

"aaaa, pero el RPSL/IRR no tiene firmas criptográficas"
Esto se habría manejado fácilmente con la adición de una capa X.509 en la
IRR.
O incluso, teniendo en cuenta que el concepto de TIR se basa en una base
distribuida, portar estas bases a un concepto de cadena de bloques (conozco
un proyecto académico que se está ocupando de esto en este momento).

Sí, sé que suena como un anciano diciendo eso:
"aaa, en mi época era mucho mejor..."
Disculpe por eso...
Pero cada día que pasa confirmo que las evoluciones protocolares son un
ejemplo puro de Razón Dialéctica, con sus tesis, antítesis y nuevas
(viejas) síntesis.
