How do you handle link state monitoring in that kind of setup?  For
example, we've got some customers with primary/backup links, and we just
route their IPs to the primary link and the backup link (with a higher
metric).  When the primary goes down, the route goes with it and the
backup route takes over.

Do you have to do dynamic routing with customers to get that effect with
your type of setup?
