Configuración de Frame Relay
Frame Relay es un protocolo WAN muy popular porque facilita la construcción de redes confiables y de bajo costo. Uno de sus principales ventajas es de poder configurar enlaces seriales punto a punto con la capacidad de conectar un sitio a muchos sitios remotos a través de un circuito físico. En este post se mostrara la configuración de Frame Relay utilizando la siguiente topologia.
Empecemos configurando el primer RouterRouter1#conf t
Enter configuration commands, one per line. End with CNTL/Z.
