3. Configure the IPv6 address on the 6to4 tunnel in the format 2002:V4ADDR::Host/16, in
which where V4ADDR is the source IPv4 address of the tunnel. The prefix length for the
tunnel must be 16.
(Netgear Switch) (Config)#interface tunnel 0
(Netgear Switch) (Interface tunnel 0)#ipv6 address 2002:c301:302::1/16
(Netgear Switch) (Interface tunnel 0)#ipv6 enable
(Netgear Switch) (Interface tunnel 0)#tunnel mode ipv6ip 6to4
(Netgear Switch) (Interface tunnel 0)#tunnel source 195.1.3.2
(Netgear Switch) (Interface tunnel 0)#exit
4. Configure the IPv6 address for routing port 1/0/3. The IPv6 address format is
2002:V4ADDR:Subnet::Host/64, in which V4ADDR is the source IPv4 address of the tunnel
and Subnet is the subnet of 2002:V4ADDR::/64.
(Netgear Switch) (Config)#interface 1/0/3
(Netgear Switch) (Interface 1/0/3)#routing
(Netgear Switch) (Interface 1/0/3)#ipv6 address 2002:c301:302:1::1/64
(Netgear Switch) (Interface 1/0/3)#ipv6 enable
(Netgear Switch) (Interface 1/0/3)#exit
5. Create a static IPv4 route to ensure that Switch 1 can reach Switch 2 and Switch 3. You can
also use a routing protocol such as RIP or OSPF to let Switch 1 learn the routes from
Switch 2 and Switch 3.
(Netgear Switch) (Config)#ip route 195.1.4.0 255.255.255.0 195.1.3.1
(Netgear Switch) (Config)#ip route 195.1.5.0 255.255.255.0 195.1.3.1
6. Because Switch 1 cannot detect the route for IPv6 address 8888::/16 (of port 2/0/24 on
Switch 3), create a static IPv6 route for Switch 1 with the tunnel address of Switch 3 as the
next hop.
(Netgear Switch) (Config)#ipv6 route 8888::/16 2002:c301:502::1
