Laboratorio Mpls Y Pppoe En Gns3

Laboratorio MPLS y PPPOE en GNS3


Esta es la topología, el R1 es el PE1, R2 es el P, el R3 es el PE2.
los R4 y 5 son CE.

Entre los P están por fastethernet y con los CE por seriales.

Ya venía una configuración pronta para no perder el tiempo configurando las interfaces y el ospf.

Bien después de tener todo esto configurado lo primero es poner a funcionar mpls y ldp, para esto usamos
los comandos:


(config)#mpls label protocol ldp
(config)#mpls ldp neighbor (el vecino que tiene directamente conectado) passwort (el passwort)


Y después se habilita la interfaz por la que van ir las tramas etiquetadas,...
