Tunnel Ipv6 sobre ipv4

Una de las maneras de migrar redes ipv4 sobre ipv6 gradualmente es configurar tuneles Ipv6 sobre ipv4

R1:

ipv6 unicast-routing

interface Loopback0

ip address 10.1.1.1 255.255.255.0

!

interface Tunnel10

no ip address

ipv6 address 12::1/64

ipv6 rip rip1 enable

tunnel source Loopback0

tunnel destination 10.2.2.2

tunnel mode ipv6ip

!

interface Serial0/0

ip address 10.10.10.1 255.255.255.252

clock rate 2000000

!

interface FastEthernet0/1

no ip address

duplex auto

speed auto

ipv6 address 2001:1::1/64

ipv6 enable

ipv6 rip rip1 enable

!
