IPv6 Neighbor Discovery Enhancements

The IPv6 Neighbor Discovery protocol performs Neighbor Unreachability Detection (NUD) in order to determine if two way communication with a neighboring node has failed. A neighbor is considered reachable if packets sent recently by the node have been confirmed as received by the neighbor. This can happen through a higher layer protocol such as TCP or by explicitly probing the neighbor via a Neighbor Solicitation. In normal operation, EOS will only perform NUD within a randomized range of 80-100% of the IPv6 Neighbor Cache expiry timeout. With this enhancement, EOS will perform NUD using a configured reachable time value. Platform...
