This depends on how flexible the PBR implementation on your router is.
If your router can have conditionals like this:

I've seen folks do things like this with a Linux box with multiple

Most if not all IGPs can be configured to work without multicast. Now if

I think they are referring to something like Cisco PBR, where you
configure routing policy statically on each hop. Yes, it can be
configured to fail over, etc, but inherently it is a management nightmare
if you are configuring PBR on each device in your network. May as well

Hi all,
We use Linux for our edge routers which have multiple interfaces to
different BGP peers. Policy based routing allows us to insure that
traffic originating from a particular external IP address on the router,
goes out the matching network.

Yes, but this is no worse than if you just had one single DSL link.
Manual failover is a perfectly valid
