Gyan,

If I understand the purpose of this draft, the point is to punch a hole in a summary so that traffic is redirected via an alternate, working path.

Rather than punch a hole, why not rely on existing technology? Have the valid path advertise the more specific. This will attract the traffic.

Tony
