Description

When the router network is discovering and maintaining the distributed understanding of the topology, router-advertisement (RA) messages are flooded across the network. Flooded messages are multicast without the tree-trimming done using valid-origins. In very redundant networks, many distinct paths are followed for these messages, using excessive amounts of network and CPU bandwidth.
