Yes, indeed! But how can I make it do so? As I said, I've played with
all the different ways to configure this that I can think of, but I
cannot get routed to announce a default route to the internal network.
(Keep in mind routed is not talking to remotegw in any way; the default
route must be statically configured.)

Well, it depends on what you consider "fast" failover. This setup should
probably fail over within a minute or two, which would be loads better
than what we have now (fails over when someone comes in and changes
everything by hand).

BTW, I'd appreciate CC's on replies to this, since I'll see those a lot
faster than I'll see them on the list.
