"if" you have a default route. Default route if multi-homed is surely bad IMHO.
Not necessarily. If you are multi-homed for redundancy reasons and have a small linux box with zebra your memory would be exhausted carrying to full route feeds. Two single default routes are far more efficient: at home I have cable and dsl. I have 2 tunnels to two different routers of my work. Over those tunnels I announce a /28 (which is aggregated to a /19) and receive two default routes. My dsl is faster so that has a higher local pref. If that goes down, the route switches over to the cable tunnel.
Well. I ACK your specific implementation. We are talking not about the small home user (or small business user). We are referring to ISP implementations here. In these ISP cases, when multihomed the "default route" is not a good idea, because of the danger of routing loops. --jan -- Jan-Ahrent Czmok http://www.lambda-solutions.de Technical Advisor ISP Hofdcker Str. 14, 65207 Wiesbaden Tel. +49-(0)-174-3074404
