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.

>>>>> 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

>>>>> in the audience to engage in facilitated dialogue.
>>>>> In addition to the background documents and papers that will be
