Pengujian

R1
R1#show ipv6 eigrp neighbors 
IPv6-EIGRP neighbors for process 10
H Address Interface Hold Uptime SRTT RTO Q Seq
(sec) (ms) Cnt Num
0 Link-local address: Gig0/0 12 00:48:06 40 1000 0 8
FE80::2 
1 Link-local address: Gig0/1 13 00:48:00 40 1000 0 12
FE80::3 


#Melalui command diatas terdapat 2 
#router pemilik link-local FE80::2 adalah R2 dan FE80::3 
#adalah R3

#Sehingga R1 sudah adjensi dengan R2 dan R3

Show ipv6 route

R1
R1#show ipv6 route 
IPv6 Routing Table - 10 entries
Codes: C - Connected, L - Local, S - Static, R - RIP, B - BGP
U - Per-user Static route, M - MIPv6
I1 - ISIS L1, I2 - ISIS L2, IA - ISIS interarea, IS - ISIS summary
O - OSPF intra, OI - OSPF inter, OE1 - OSPF ext 1, OE2 - OSPF ext 2
ON1 - OSPF NSSA ext 1, ON2 - OSPF NSSA ext 2
D - EIGRP, EX - EIGRP external

via GigabitEthernet0/2, directly connected
L 2001:DB8:DEF:1::1/128 [0/0]
via GigabitEthernet0/2, receive
D 2001:DB8:DEF:2::/64 [90/3072]

Flag D berarti menggunakan routing EGIRP, 
contohnya, untuk menuju network 2001:DB8:DEF:2::/64, 
R1 akan melewati R2, 
hal ini dapat dilihat dari link-local FE80::2

D 2001:DB8:ABCD:23::/64 [90/3072]
via FE80::2, GigabitEthernet0/0
via FE80::3, GigabitEthernet0/1
L FF00::/8 [0/0]
via Null0, receive
R1#

#Fungsi link-local ini mempermudah 
#network administrator dalam melihat 
#route, jika tidak dikonfigurasi, 
#Router akan membuat link-local 
#dengan kombinasi prefix FE80::/10 
#dengan MAC Address fisik
#sehingga menyulitkan 

#Untuk routing yang menuju 
#2001:DB8:ABCD:23::/64, 
#terdapat 2 route yakni bisa melewati 
#R2 dan R3, hal ini bisa terjadi 
#karena keduanya mempunyai cost yang sama.
