- setup a 6to4 relay + route 192.88.99.1 + 2002::/16
How?
Listing 11-7. A Cisco 6to4-to-IPv6 Gateway Configuration ! interface Loopback2002 ip address 192.88.99.1 255.255.255.255 ! interface Tunnel2002 ipv6 enable ipv6 mtu 1280 tunnel source 192.88.99.1 tunnel mode ipv6ip 6to4 ! Listing 11-8. A Private 6to4 Gateway in the IPv6-to-6to4 Direction ! interface Tunnel2002 ipv6 address 2002:DFE0:E1E2::/16 ipv6 mtu 1280 tunnel source 223.224.225.226 tunnel mode ipv6ip 6to4 ! Assuming you have already configured your normal IPv6 connectivity (you havent!? http://www.bgpexpert.com/presentations/ ipv6_tutorial.pdf ). Don't forget to sprinkle some "redistribute connected" over your favorite routing protocols and you're in the 6to4 gatewaying business. If you want to run a public gateway, announce 192.88.99.0/24 and 2002::/16 over BGP. Iljitsch -- I've written another book! http://www.runningipv6.net/
