Ejemplo: Configuración de la directiva de selección de copia de seguridad para el protocolo OSPF u OSPF3
En este ejemplo se muestra cómo configurar la directiva de selección de copia de seguridad para el protocolo OSPF u OSPF3, que permite seleccionar una alternativa sin bucles (LFA) en la red.
Cuando se habilitan las directivas de selección de copia de seguridad, Junos OS permite la selección de LFA en función de las reglas de política y los atributos de los vínculos y nodos de la red. Estos atributos son admin-group, srlg, ancho de banda, tipo de protección, métrica y nodo.
Requisitos
En este ejemplo, se utilizan los siguientes componentes de hardware y software:
Ocho enrutadores que pueden ser una combinación de enrutadores de borde multiservicio serie M, plataformas de enrutamiento universal 5G serie MX, enrutadores de transporte de paquetes serie PTX y enrutadores de núcleo serie T
Junos OS versión 15.1 o posterior ejecutándose en todos los dispositivos
Antes de empezar:
Configure las interfaces del dispositivo.
Configure OSPF.
Descripción general
En Junos OS, el algoritmo o criterio de selección de alternativa sin bucles (LFA) predeterminado se puede anular con una política LFA. Estas políticas se configuran para cada destino (IPv4 e IPv6) y una interfaz principal de próximo salto. Estas políticas de copia de seguridad imponen la selección de LFA en función de los atributos de grupo de administración, srlg, ancho de banda, tipo de protección, métrica y nodo de la ruta de copia de seguridad. Durante el cálculo de la ruta más corta (SPF) de la copia de seguridad, IGP acumula cada atributo (tanto el nodo como el vínculo) de la ruta de copia de seguridad, almacenado por el próximo salto de la copia de seguridad. Para las rutas creadas internamente por IGP, el conjunto de atributos de cada ruta de copia de seguridad se evalúa con respecto a la política configurada para cada destino (IPv4 e IPv6) y una interfaz principal de próximo salto. Se selecciona la primera o la mejor ruta de copia de seguridad y se instala como el siguiente salto de copia de seguridad en la tabla de enrutamiento. Para configurar la directiva de selección de copia de seguridad, incluya la instrucción de configuración en el nivel de jerarquía.backup-selection[edit routing-options] El comando muestra las directivas configuradas para una interfaz y un destino determinados.show backup-selection La visualización se puede filtrar según un destino, prefijo, interfaz o sistema lógico determinados.
Topología
En esta topología que se muestra en , la directiva de selección de copia de seguridad se configura en el dispositivo R3.Figura 1

Configuración
Configuración rápida de CLI
Para configurar rápidamente este ejemplo, copie los siguientes comandos, péguelos en un archivo de texto, elimine los saltos de línea, cambie los detalles necesarios para que coincidan con su configuración de red, copie y pegue los comandos en la CLI en el nivel de jerarquía [edit] y, luego, ingrese commit desde el modo de configuración.
