Amazing.  Last I looked NetBSD's routed spoke only RIP v1 and that
doesn't really support subnets.

I presume with "my ISP's router" you mean their terminal server that
handles your PPP link.  Or, more accurately, the router with the IP
address that's configured as the "destination" of your PPP interface.

That's because it hasn't received any RIP packets from the IP address
at the other side of the PPP link.  See why that box doesn't speak RIP
to you.

That's because, since routed has decided that there is no RIP-speaking
router at the other side of the PPP link (indicating that the link is
not working) hence it won't send RIP packets over PPP link.

>Anyone know how to tell routed not to delete a particular route, every time?

Check your configuration or declare the real RIP-router at your ISP as
a distant gateway in /etc/gateways.  You probably want to declare it
as distant passive gateway.

It's all in routed(8), BTW.
