Now, this is the kind of situation the various design certs should test on!
&;-)
Regarding your actual question, have you considered a Layer-8 solution?
Depending on who you talk to, Layer 8 deals with money, politics, planning,
etc. My thinking is that you should select a provider that gives you peace
of mind regarding resiliency within the provider's network. Howard talked
about scope. Worrying about routes failing within your provider's network
should be outside your scope. Sure, you might have to pay extra for this
"peace of mind." But can you get a service-level agreement that gives you this?
Now, if your link to the provider dies, then you should be able to failover
to the other provider. That much is within your scope. But worrying about
routes within your providers' networks should theoretically be outside your
scope.
