Selanjutnya kita konfigurasikan 6to4 tunnel pada R2 dan R3

R2,
 interface tunnel 0
 ipv6 address 2000::/64 eui-64
 tunnel source Ethernet 1/0 
 tunnel mode ipv6ip isatap
 exit

R3,
 interface tunnel 0
 ipv6 address 2000::/64 eui-64
 tunnel source Ethernet 1/0 
 tunnel mode ipv6ip isatap
 exit

R4,
 interface tunnel 0
 ipv6 address 2000::/64 eui-64
 tunnel source Ethernet 1/0 
 tunnel mode ipv6ip isatap
 exit
