It's not easy because it's currently not possible. :) There's nothing
wrong with this idea, it's just not something we (currently) implement.
That works OK as long as all you need to do is avoid the link/node
you're protecting. If you explicitly need to steer a path in a
specific direction (so you don't protect an OC48 down an OC3, for
example), you then need to start explicitly steering LSPs, which means
you need to build a tunnel interface and so forth.
