Escenario integrador de VLANs
e IPv6
Fecha: 2 de Agosto 2013
Clase: CCNA 3, con alumnos ya calificados para CCNA 4.
Escenario
El escenario es un típico
de router on a stick de CCNA 3 y sólo como método de adaptación para IPv6.
La topología de
enrutamiento es la clásica de CCNA 2 y el direccionamiento de red está heredado
del
libro ICND2 de Wendell
Odom. Podría haber sido más real (y tedioso) como puede resultar ser IPv6 al
comiezo de su estudio. Eso
lo dejamos para los capítulos finales de CCNA 4 v4.
Por motivos de
simplicidad, el escenario fue ligeramente distinto, sin el router ISP, formando
un punto
a punto entre Rosario y
BsAs. Este documento está redactado unos días antes.
Objetivo:
1) Configurar sucursal BsAs basado en la config
de Rosario.
2) Agregar SW nuevo
y configurar VTP, vlans e inter-vlan.
