La empresa tiene 3 sedes

Cada una de las sedes tiene una IP pblica

Acceden a Internet con un NAT en el router de cada una de las sedes

La interconexin entre sedes se realiza con un tnel GRE con ESP_AES

Entre las sedes dentro del tnel GRE usan EIGRP

En cada sede tenemos 3 VLANs

El ISP actual an no tiene soporte IPv6

Planificamos un cambio de ISP, pero este proceso puede durar unos 3 meses, entre instalaciones en cada una de las sedes, configuraciones

Como que es necesario acceder a la red de la empresa colaboradora DSW quiere asignar las direcciones IPv6 en sus redes internas

Y llegaran a la empresa colaboradora con un tnel IPv6IP esttico.

La red IPv6 asignada por el operador es 2001:DB8:CAFE::/48

En este escenario un buen mtodo podra ser

Stateless DHCP V6

ipv6 unicast-routing

interface FastEthernet0/0.10

ipv6 address 2001:DB8:CAFE:110::1/64

ipv6 nd other-config-flag

ipv6 dhcp server DHCPv6

ipv6 dhcp pool DHCPv6

dns-server 2001:DB8:BEEF::10

domain-name dsw.com

El tnnel ipv6ip

!Router principal

interface Tunnel3

ipv6 address 2001:DB8:CAFE:FFFD:1/64

tunnel source Serial0/0/0

tunnel destination 209.165.200.253

tunnel mode ipv6ip

!

ipv6 route 2001:DB8:BEEF::/48 2001:DB8:CAFE:FFFD::2

Como que en IPv4 usamos eigrp sera bueno continuar con eigrp

ipv6 router eigrp 1

router-id 1.1.1.1

redistribute static 64 2000 255 1 1500

no shutdown

interface FastEthernet0/0.10

ipv6 eigrp 1

interface FastEthernet0/0.20

ipv6 eigrp 1

interface FastEthernet0/0.30

ipv6 eigrp 1

interface tunnel 0

ipv6 eigrp 1

Thank you.

Gracias.
