Ipv6

To my amazement, Telecom Italia released a pilot project of IPv6 deployment on residential/dynamic ip only adsl internet access, but on theirs support site there’s configuration only for some useless systems. So, I’ve decided to write a configuration for Cisco platform. Usually the typical Telecom Italia PPPoE or PPPoA ADSL connection with dynamic IPv4 only was authenticated with “aliceadsl” as user and password, now with bran new credential along IPv4 the endpoint router advertise a IPv6 /64 class (always dynamic). ...

Memo about configure ipv6 on OpenVMS system as host mode: First of all invoke the TCPIP$IP6_SETUP command procedure by entering the following command: TARDIS::LEO$ @SYS$MANAGER:TCPIP$IP6_SETUP Leaving default option to all question, in this mode the dcl create default configuration script. Then edit the inet6 script: TARDIS::LEO$ EDIT SYS$SYSTEM:TCPIP$INET6_CONFIG.DAT After the “up” command $ ifconfig "IE0" ipv6 up Append the following line with ip and default gateway: $ ifconfig "IE0" inet6 ip6prefix 2001:1418:0193:0001::40/64 $ route add -inet6 default 2001:1418:0193:0001::250 -"I" "IE0" Save, exit and run the dcl: ...

You need to update and configure following files for IPv6 configuration: Edit: /etc/sysconfig/network And append following line, to enable in systemwide the ipv6 protocol: NETWORKING_IPV6=yes Edit: /etc/sysconfig/network-scripts/ifcfg-eth1 (or your interface number) And append following line, to enable ipv6 on interface and the address/gateway if you use static routing: IPV6INIT=yes IPV6ADDR=2001:1418:0193:000B::210 IPV6_DEFAULTGW=2001:1418:0193:000B::251 Save, close and restart network service: # service network restart

Come definire il link ad un tunnel broker i questo esempio HE.net da sistema operativo linux utilizzando i net tools Prima parte crea l’interfaccia di tunneling sull’ipv4: ifconfig sit0 up ifconfig sit0 inet6 tunnel ::216.66.84.42 Seconda parte genera l’endpoint del tunnel in ipv6: ifconfig sit1 up ifconfig sit1 inet6 add 2001:470:1f12:11c::2/64 Terza parte definisce la rotta sul device relativo all’endpoing del tunnel per tutto il traffico ipv6: route -A inet6 add ::/0 dev sit1

Simpatica certificazione IPv6 inventata dalla Hurricane Electric:

Anche se non credevo che fosse cosi’ semplice i tunnel 6to4 sui router cisco non sono una cosa complessa come sembra posto uno straccio di configurazione usato con il tunnel broker Hurricane Electric sul server di parigi: interface Tunnel0 no ip address no ip redirects no ip unreachables no ip proxy-arp ipv6 address 2001:470:1F12:10A::2/64 ipv6 enable tunnel source xxx.xxx.xxx.xxx tunnel destination 216.66.84.42 tunnel mode ipv6ip ! ipv6 route ::/0 Tunnel0 Attenzione questa e’ usata su un 2600 con IOS 12.3 IP FW IDS PLUS / IPSEC Ricordo che e’ bene inserire un ACL che faccia passare il protocollo 41 solo dall’end point del tunnel e ovviamente lasciare le risposte icmp abilitate

Visto che ogni tanto sale l’inutile fobia dell’imminente fine degli IP4 (cosa che reputo ridicola) ho deciso che era il momento di muovere un po’ la mia rete dato che iniziava ad essere abbastanza monotona. Quindi dal 22 Luglio ho allocate due classi di ip: 2001:470:c86f::/48 2001:470:1f13:10a::/64 Gia’ che ero in vena di novita’ c’e’ pure un nuovo dominio stars6.net dedicato alle prove del caso.
