Final práctico CCNA 2 ( Exploration 2 ) 2do semestre 2009

Prácticas realizadas entre el 19 y 23 de Diciembre del 2009

Instructor: Ernesto Vilarrasa

Escenario: este escenario está compuesto por dos sitios ( casa central Rosario y sucursal Córdoba )

los cuales están vinculados por dos proveedores de comunicaciones para dar redundancia.

Este escenario debe configurarse con EIGRP y OSPF en cada site respectivamente, unidos por

rutas por defecto.

En sucursal, los dos gateways tienen configurados pools DHCP para dar soporte de gateway en

caso de falla de alguno de los routers.

La conectividad redundante debe comprobarse mediante la caída de enlaces.
