ariel.
gracias por responder. esa variante no implicaría el uso de una dirección IP adicional? ya estoy casi al límite con las IP públicas disponibles...

Hola Manuel.


Quizás la solución más fácil es que aproveches las ventajas del ECMP (equal cost multi path), esto se hace de form automática cuando tienes dos rutas con la misma métrica, la misma distancia administrativa y la misma red de destino.


Si corres un IGP, esto puede llegar a hacerse sin intervención tuya al ver caminos perfectamente iguales al mismo destino. Sino, vas a tener que poner algunas rutas estáticas (con tracking e ip sla) para que se vuelvan nulas al no responder el otro lado.


Claro está, esto no sirve para interfaces bridgeadas, solo ruteadas.


Cualquier cosa me contactas por unicast y te paso algunos ejemplos.


Saludos!

  no.., esto no sería lo que estas buscando.

  Tu respuesta en el mundo de Cisco es etherchannel ..., nunca lo ví en routers pero si en LAN Switches. No se si exista alguna solución más moderna y que yo me haya quedado en la prehistoria :-|


  Saludos,

  Ale,

      Hola,
      Alguien sabe como configurar un router cisco (tal vez un 2900 o 2800) con dos interfaces de red
      ethernet redundantes? algo parecido a lo que llamamos en linux interfaces bond?
      Saludos,

        Estimados colegas,


        Estoy organizando una session sobre IPv6 en el Foro de Governance que
        tendrá lugar en Mexico al mes que viene.

        Me encantaría incluir la participación de personas responsable del
        despliegue de IPv6 de Latin America. A continuación os incluyo detalles
        de la session.

        Si teneis alguna pregunta, envíame una nota.

        saludos

        Roberto

        IGF 2016 Workshop #6 : Can Law enforcement catch bad actors online
        anymore

        https://www.intgovforum.org/cms/igf2016/index.php/proposal/view_public/6 

        Description of workshop:

        The exhaustion of the IPv4 address supply has been predicted since the
        end of the 1980s. However, the large scale adoption of mobile devices
        and their associated IPv4 addressing needs accelerated the exhaustion
        timetable, and placed increased pressure on network operators to
        conserve IPv4 addresses

        This pressure has resulted in a marked increase in the use of
        technologies, such as Network Address Translation (NAT), that allow
        pools of addresses to be shared across multiple endpoints. These
        mechanisms enable the reuse of the limited pool of available IPv4
        addresses, resulting in the number of connected endpoints vastly
        outnumbering the number of addresses in use in the public internet.

        This has three important implications for Internet technology
        developers, and those who depend on certain behaviors of the technology.

        Application designers need to consider the fact that an IP address does
        not necessarily identify an endpoint.

        Law enforcement and forensic functions need to consider that an IP
        address alone may not be sufficient to correlate Internet activity
        observations with an endpoint; and even an IP address associated
        timestamp generally may not suffice.

        Data retention mechanisms and policies that record or reference an IP
        address need to refactor their actions and requirements to consider that
        in increasingly large parts of the Internet, an IP address is merely a
        temporary identifier. Potentially large volumes of ancillary data are
        required to match an IP address to an endpoint.

        Description of the plan to facilitate discussion amongst speakers,
        audience members and remote participants:

        The workshop will be organized as a facilitated dialogue. Led by the
        moderator, subject experts will debate and discuss the key questions and
        issues. Subject experts will give opening comments, after which the
        moderator will turn to those attending the session and invited experts
        in the audience to engage in facilitated dialogue.

        In addition to the background documents and papers that will be prepared
        ahead of the IGF, additional articles of interest, commissioned blogs,
        reference materials and social media conversations will be published and
        distributed ahead of the workshop.

        Speakers:

        The experts listed below have accepted the invitation to participate in
        the session. They are drawn from the Law Enforcement, Government,
        Academia, Civil Society, The Technical Community and Private sector
        stakeholder groups. A facilitated dialogue will be organized so that
        these experts can bring their knowledge and perspective to discuss and
        debate the challenges brought by IPv4 exhaustion and the challenges and
        opportunities presented by IPv6 adoption.
