Loadsharing is usually pretty good, this depends *very*much* to whom you are connected, and how. Please remember that one of the main points in BGP is not automatic, but policy - not only your own, but that of other people on the 'Net as well. Best, --Toni++

The only caveat with BGP on OpenBSD is that you cannot do equal cost load balancing. For instance, if your providers send you a default route, you can only install 1 of those routes in the routing table (due to the current multipath route limitation in OpenBSD). All this means though is that all traffic being routed to the default route will use one pipe instead of both (i.e., one pipe will most likely be much less used than the other). For most people this is a non-issue. The ins and outs of setting BGP up is beyond what can be described in this thread and that's why I recommended a good book right from the start :) .joel

You might also want to read http://www.inetdaemon.com/columns/ask/internet-load-balancing.shtml, which will try to talk you out of using BGP for load balancing and present a simpler alternative. j knight wrote: --- Quoting Karl O.

Does bgp/OpenBGP have any provisions for load balancing, say based on WAN link latency? (Seems like this _could_ be a bgp policy at the local level, but nothing leaps out at me from bgpd.conf(5).)

This solution talks about using dual static routes. This doesn't (yet) work on OpenBSD as the support isn't there. Best bet if this track is taken is to involve pf's load balancing features (http://www.openbsd.org/faq/pf/pools.html and pf.conf(5)). .joel
