[lacnog] Consulta sobre cisco

Mie Nov 9 18:29:42 BRST 2016

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.
