Lab — IPv6 Base
Configura IPv6 su un router con 2 LAN. Assegna GUA, link-local, abilita il routing IPv6, verifica con show e testa con ping6.

1Abilita routing IPv6
enable → conf t
ipv6 unicast-routing
⚠️ Senza questo, R1 non instrada IPv6!

2Configura Gi0/0 (LAN A)
interface Gi0/0
ipv6 address 2001:db8:a:1::1/64
ipv6 address fe80::1 link-local
no shutdown
ipv6 address 2001:db8:a:1::1/64
ipv6 address fe80::1 link-local
no shutdown
3Configura Gi0/1 (LAN B)
interface Gi0/1
ipv6 address 2001:db8:b:1::1/64
ipv6 address fe80::1 link-local
no shutdown
ipv6 address 2001:db8:b:1::1/64
ipv6 address fe80::1 link-local
no shutdown
4Verifica
show ipv6 interface brief
show ipv6 route
show ipv6 neighbors
show ipv6 route
show ipv6 neighbors
5Test connettività
Da PC1:
ping 2001:db8:a:1::1 (gateway) → ✅
ping 2001:db8:b:1::10 (SRV1, altra LAN) → ✅ via R1
ping 2001:db8:a:1::1 (gateway) → ✅
ping 2001:db8:b:1::10 (SRV1, altra LAN) → ✅ via R1
💡 Link-local fe80::1 è lo stesso su entrambe le interfacce — è valido perché link-local è per-link, non globale. I PC usano fe80::1 come default gateway IPv6.
