Implementar OSPF Lab Multilayer Switches y Routers:
Configurar Core1, Core2, R1, R2 y R3
1.- Usar process ID 1, y todas las redes dentro de area 0.
2.- Usar 32 bits declaraciones de red exactas para loopback.
3.- Usar declaraciones de red /21 para NV, VA, y ZA /21.
4.- Para la red 10.16.7.0/28 utilizar coincidencia exacta.
Wildcard mask 32 = 0.0.0.0
Wildcard mask /21 = 0.0.7.255
Wildcard mask /28 = 0.0.0.15
Bloque de direcciones NV = 10.16.0.0/21
Bloque de direcciones VA = 10.16.0.0/21
Bloque de direcciones ZA = 10.16.0.0/21
