Loopbacks on Cisco routers are good - accessible from any interface, you just
need to make sure routes to them are published in your routing protocol.
Combine this with monitoring interface status, and you can tell when an
interface has gone down, for example.
I'm close to implementing this on a bunch of our routers, which have an
Internet-facing IP address for the host, a VPN-service specific loopback
address which I monitor as the service "vpn-service", and two tunnel
interfaces, one of which can be "down".
