 Configuración de EIGRP.

"Topología de red Implementada"

Descripción: En la siguiente imagen se muestran 2 routers en un mismo AS que comparten sus rutas internas a través de EIGRP.

 ¿Qué es EIGRP?:

EIGRP, o Enhanced Interior Gateway Routing Protocol (Protocolo de Enrutamiento Avanzado para Redes Internas), es un protocolo de enrutamiento de vector de distancia avanzado desarrollado por Cisco. EIGRP es considerado un protocolo de enrutamiento híbrido, ya que combina características de protocolos de vector de distancia y de estado de enlace para proporcionar un enrutamiento eficiente y confiable en redes IP.
