Lab 1. Dasar IPv6

 1a. Link-Local Unicast Address (automatic) Mengaktifkan IPv6, karena secara default tidak diaktifkan.

R1:

R1(config)#ipv6 unicast-routing

R2:

R2(config)#ipv6 unicast-routing

Khusus pada Switch L3, modulnya ipv6 nya harus diload terlebih dahulu.

Example:

SW(config)#sdm prefer dual-ipv4-ipv6 default

SELANJUTNYA HARUS RELOAD

Setiap kali kita setting IPv6 pada sebuah interface, maka Link-Local Unicast Address akan muncul secara otomatis pada interface tersebut. Namun kita bisa juga mengkonfigurasikannya secara manual. Nilainya selalu diawali dengan FE80::/10.

Perintah berikut akan membuat Link-Local Unicast Address secara otomatis pada interface setiap kita mengaktifkan interface tersebut untuk konfigurasi IPv6.

R1:

R1(config)#int fastEthernet 0/0

R1(config-if)#ipv6 enable

R1(config)#no sh

R1(config-if)#exit

R2:

R2(config)#int fastEthernet 0/0

R2(config-if)#ipv6 address autoconfig

R2 (config-if)#no sh

Kemudian cek interfacenya.

R1:

R1#sh ipv6 interface f0/0 | i link-local

IPv6 is tentative, link-local address is FE80::C801:4FF:FEFC:8 [TEN]

No Virtual link-local address(es):

R1#sh ipv6 int brief

FastEthernet0/0 [administratively down/down]

    FE80::C801:4FF:FEFC:8

FastEthernet0/1 [administratively down/down]

    unassigned

GigabitEthernet1/0 [administratively down/down]

    Unassigned

Berikut penjelasan nilai link-local address yang didapat dari nilai mac-address.

1b. Global Unicast Address

R1:

R1(config)#int fastEthernet 0/0

R1(config-if)#ipv6 address

R1(config-if)#ipv6 address 12::1/126

R1(config-if)#no shutdown

R1(config-if)#exit

R1(config)#do show ipv6 int brief

FastEthernet0/0 [up/up]

    FE80::C801:4FF:FEFC:8

    12::1

R2:

R2(config)#int f0/0

R2(config-if)#ipv6 address 12::2/126

R2(config-if)#no shutdown

R2(config-if)#exit

R2(config)#do sh ipv6 int brief

FastEthernet0/0 [up/up]

FE80::C802:5FF:FE0C:8

12::2

Coba lakukan tes ping.

R1:

R1(config)#do ping 12::2

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 12::2, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/15/36 ms

R2:

R2(config)#do ping 12::1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 12::1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 8/16/20 ms

1c. EUI-64 Address

R1:

R1(config)#int fastEthernet 0/0

R1(config-if)#ipv6 add 21::/64 eui

R1(config-if)#ipv6 add 21::/64 eui-64

R1(config-if)#exit

R1(config)#do sh ipv6 int brief

FastEthernet0/0 [up/up]

    FE80::C801:4FF:FEFC:8

    12::1

     21::C801:4FF:FEFC:8

R2:

R2(config)#interface f0/0

R2(config-if)#ipv6 address 21::/64 eui-64

R2(config)#do sh ipv6 int brief

FastEthernet0/0 [up/up]

FE80::C802:5FF:FE0C:8

12::2

21::C802:5FF:FE0C:8
