peter, tony and henning, thx for the info about the scale at which BGP is useful. i now see that the scale i was considering it isn't useful. the motivation for asking this is that i'm running an ecommerce website from work and am interested in having a failover and/or loadbalancing for it in the event that the power goes out at work, etc. colocating the machine that serves it is probably the best idea, but i was trying to be cheap and work with what i already have available (the 2 ADSL connections + old hw). i think CARPing machines when they're in different public IP blocks won't work, i.e. x.y.z.w/29 and a.b.c.d/29 cannot have a single address CARPed across blocks. do tell if i'm wrong on this one since this would work nicely for the situation i've described. cheers, jake >-- >BS Web Services, http://www.bsws.de/ >OpenBSD-based Webhosting, Mail Services, Managed Servers, ... >Unix is very simple, but it takes a genius to understand the simplicity. >(Dennis Ritchie)
