 Configuración de OSPFv2.

"Topología de red Implementada"

Descripción: En la siguiente imagen se muestran 3 Router Cisco ISR S4300 conectados directamente usando el protocolo de enrutamiento OSPFv2.

 ¿Qué es OSPF?:

OSPF, o Protocolo de Enrutamiento de Estado de Enlace (Open Shortest Path First), es un protocolo de enrutamiento interior utilizado en redes de computadoras para determinar las rutas más eficientes para el envío de paquetes de datos. Fue diseñado para funcionar en redes IP y es uno de los protocolos de enrutamiento más ampliamente utilizados en redes empresariales y proveedores de servicios.
