Routing Estático IPV6

Este artículo forma parte de una serie de varios artículos que tratan los distintos tipos de routing en IPV4 e IPV6 para CCNA R&S, para ir al índice del curso tienes este link:

Routing Estático IPV6

El routing estático en IPV6 es exactamente el mismo que para IPV4, solamente cambia que donde antes poníamos IP, ahora ponemos IPV6 :-D, por lo demás el concepto es el mismo, teniendo en cuenta que las direcciones y máscaras en IPV6 son un poco mas feas.

De hecho hay que decir que una tabla de rutas en IPV6 es muy muy fea de leer. A primera vista es tan legible como el coreano, pero según vas trabajando con ello le vas cogiendo algo mas de cariño, aunque eso no quita que sean difíciles de leer.

Configuracion de rutas estáticas en IPV6:

Ipv6 route <RED_DESTINO>/<MASCARA_DE_RED> <SIGUIENTE_SALTO>

Ejemplo routing estático ipv6:

Este es el mapa de nivel FISICO.

 Este en cambio es el nivel LÓGICO.

 
R1:

ipv6 unicast-routing

interface Loopback0

ipv6 address 1111::1/128

interface FastEthernet0/0

ipv6 address 2020:1::1/64

ipv6 route ::/0 2020:1::4

R2(Router on a Stick):

ipv6 unicast-routing

interface Loopback0

 ipv6 address 2222::2/128

 interface FastEthernet0/0.2
 encapsulation dot1Q 2
 ipv6 address 2020:2::2/64

!

interface FastEthernet0/0.3

 encapsulation dot1Q 3

 ipv6 address 2020:3::2/64

ipv6 route 3333::3/128 2020:3::3

ipv6 route ::/0 2020:2::4
