Selanjutnya kita konfigurasikan 6to4 tunnel pada R2 dan R3 Perhitungan IPv6 address-nya bisa di bantu dengan https://www.calculator.net/ip-subnet-calculator.html

R2,

interface tunnel 0 
ipv6 address 2002:0c0c:0c02::2/64 
tunnel source Ethernet 1/0 
tunnel mode ipv6ip 6to4 
exit

R3,

interface tunnel0
ipv6 address 2002:0d0d:0d03::3/64 
tunnel source Ethernet 1/0
tunnel mode ipv6ip 6to4 
exit

R4,

interface tunnel0
ipv6 address 2002:0e0e:0e04::4/64 
tunnel source Ethernet 1/0
tunnel mode ipv6ip 6to4 
exit

Set routing

R2,

ipv6 unicast-routing
ipv6 route 2002::/16 tunnel 0
ipv6 route 2001:4:5:6::/64 2002:0d0d:0d03::3
ipv6 route 2001:7:8:9::/64 2002:0e0e:0e04::4

R3

ipv6 unicast-routing
ipv6 route 2002::/16 tunnel 0
ipv6 route 2001:1:2:3::/64 2002:0c0c:0c02::2
ipv6 route 2001:7:8:9::/64 2002:0e0e:0e04::4

R4,

ipv6 unicast-routing
ipv6 route 2002::/16 tunnel 0
ipv6 route 2001:1:2:3::/64 2002:0c0c:0c02::2
ipv6 route 2001:4:5:6::/64 2002:0d0d:0d03::3

Cek

R2

do show interface tunnel 0
do show ipv6 route
do ping 2001:4:5:6::1
do ping 2001:7:8:9::1

R3

do show interface tunnel 0
do show ipv6 route
do ping 2001:1:2:3::1
do ping 2001:7:8:9::1

R4,

do show interface tunnel 0
do show ipv6 route
do ping 2001:1:2:3::1
do ping 2001:4:5:6::1
do ping 2001:7:8:9::1

Setup Virtual PC
