These Tree Notifications are initiated by a node detecting the failure to a Repair Node downstream. A Repair Node is a node that has a pre-built backup path that can circumvent the failure. Using this mechanism, a Repair Node has the ability to learn about non-local failures quickly without having to wait for the IGP to convergence. This draft also covers an optional method to avoid bandwidth usage on the pre-built backup path.}, }
