Abstract
Método y aparato para la sincronizacion LDP-IGP en las redes de difusion. En una realizacion de la solicitud, en respuesta a un elemento de red que presenta una adyacencia con un enrutador designado de la red de difusion en una interfase de difusion, ese elemento de red informa en su notificacion de estado de enlace (LSA) una adyacencia de par a par (P2P) a cada miembro de la red de difusion que tiene comunicacion IGP bidireccional con el elemento de red, en lugar de notificar una adyacencia de pseudo-nodo al pseudo-nodo de la red de difusion. Cada adyacencia P2P incluye un alto costo para desalentar el uso de esos enlaces para el tráfico de transmision. Una vez que el LDP se vuelve operativo con todos los vecinos de la interfase de difusion, el elemento de red notifica la adyacencia de pseudo-nodo en lugar de las adyacencias P2P. Por consiguiente, se evita el tráfico de transmision a través de ese elemento de red hasta que el LDP está operativo con todos los vecinos de la interfase de difusion.
