Lab — Route Statiche IPv6
2 router (R1, R2) con 2 LAN IPv6. Abilita ipv6 unicast-routing, configura GUA + link-local, route statiche con next-hop link-local (fully specified), default route ::/0. Verifica e ping6.

1ipv6 unicast-routing su R1 e R2
enable → conf t → ipv6 unicast-routing
⚠️ Fai su ENTRAMBI i router!

2Configura R1 interfacce
int Gi0/0 → ipv6 address 2001:db8:a:1::1/64 → ipv6 address fe80::1 link-local → no shut
int Gi0/1 → ipv6 address 2001:db8:link:1::1/64 → ipv6 address fe80::1 link-local → no shut
int Gi0/1 → ipv6 address 2001:db8:link:1::1/64 → ipv6 address fe80::1 link-local → no shut
3Configura R2 interfacce
Gi0/1: 2001:db8:link:1::2/64 + fe80::2
Gi0/0: 2001:db8:b:1::1/64 + fe80::2
Gi0/0: 2001:db8:b:1::1/64 + fe80::2
4Route statica su R1 (fully specified)
ipv6 route 2001:db8:b:1::/64 Gi0/1 fe80::2
next-hop link-local → serve exit-if!
next-hop link-local → serve exit-if!
5Default route su R2
ipv6 route ::/0 Gi0/1 fe80::1
R2 è stub: tutto verso R1.
R2 è stub: tutto verso R1.
6Verifica e test
show ipv6 route su entrambi
Da PC1: ping 2001:db8:b:1::10
Da PC1: ping 2001:db8:b:1::10
💡 Fully specified = exit-if + next-hop link-local. Obbligatorio perché fe80 è ambiguo!
