carlos, ese router solo tiene atrás servidores de la nube.
mi idea fue aprovechar la interface que tiene sin uso y conectarla a otro switch. válido comentar que no me puedo poner a inventar mucho con ese router, está en servicio y cualquier cambio implica fallos y tiempo de desconexión ...

Lo que dice Ariel tiene mucho sentido si lo que está atrás de ese router son otros routers, o algo que hable IGPs.
Si son servers o hosts nomas, ahi no sería tan útil. Si bien uno puede correr quagga o bird en ellos, en general es demasiada complejidad para configuraciones usualmente muy simples.
Creo que lo que quieres lograr lo podrías lograr usando bridging, las interfaces BVI por ejemplo.

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 :-|

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?

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
