ROUTE_POLICY_PRIORITY: the priority for this policy,
such as1`.
ROUTE_POLICY_MATCH_EXPRESSION: Es una expresión que debe coincidir con esta política de ruta.
ROUTE_POLICY_ACTIONS_EXPRESSION: Acciones para esta política de enrutamiento
Por ejemplo, el siguiente comando crea una política de BGP para establecer el valor del atributo del discriminante de salidas múltiples (MED) de BGP en 12345 para las rutas de BGP que no se incluyen en 192.168.10.0/24 y que coinciden con el conjunto de comunidades de BGP 65000:1 y 65000:2.
Reemplaza ROUTE_POLICY_PRIORITY por la prioridad que desees para esta política, como 1.
Sube una política de ruta de BGP
Crea la política de ruta de BGP en tu editor de texto preferido. Puedes usar el formato JSON o YAML para crear tu política de ruta de BGP. En el siguiente ejemplo, se usa un archivo YAML:
BGP_ROUTE_POLICY_NAME: un nombre para la política de ruta de BGP.
ROUTE_POLICY_TYPE: el tipo de política de ruta de BGP que creas. El tipo puede ser uno de los siguientes:
ROUTE_POLICY_TYPE_IMPORT: Políticas de ruta de BGP para rutas entrantes.
ROUTE_POLICY_TYPE_EXPORT: Políticas de ruta de BGP para rutas salientes.
ROUTE_POLICY_PRIORITY: Es la prioridad de esta política, como 1.
ROUTE_POLICY_MATCH_EXPRESSION: Es una expresión que debe coincidir con esta política de ruta.
ROUTE_POLICY_ACTIONS_EXPRESSION: Acciones para esta política de enrutamiento
Por ejemplo, el siguiente comando de archivo YAML crea una política de BGP para rutas entrantes que establece el valor del atributo del discriminante de salidas múltiples (MED) de BGP en 12345 para las rutas de BGP que no se incluyen en 192.168.10.0/24 y que coinciden con el conjunto de comunidades de BGP 65000:1 y 65000:2.
