You're running Red Hat Linux 7.1 or later. - - This is required for correct IPv6 by default settings, and IPv6 being - enabled as a kernel module by default. You also need recent enough - initscripts, provided in RHL71. - -2. You have a static, globally unique IPv4 address. - -3. Protocol 41 (IPv6-in-IPv4) is not being filtered in any IPv4 firewall. - -4. 'iproute' package is installed. This is used by default for a lot - more powerful tunneling capabilities. - -INFORMATION NEEDED ------------------- - -You need to know: - -1. The IPv4 address of your tunnel end point -2. The IPv6 address used in your tunnel - -The other end needs to know the same things about your setup. - -NOTE: It is also possible to set up unnumbered tunnels (no global IPv6 -addresses). - -You must get these from a party (tunnel broker) who's assigning IPv6 tunnels. See: -http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/IPv6-HOWTO-1.html#joinIPv6backbone - -Example from http://old.freenet6.net: ---- -This script will create a tunnel between this computer -and the Freenet6 server (tunnels server) -Your IPv6 address (your tunnel end point) is -3ffe:b00:c18:1fff:0:0:0:7f5 -We establish a tunnel to the Freenet6 server at -3ffe:b00:c18:1fff:0:0:0:7f4 -Your IPv4 address is : 193.xxx.yyy.zzz -The IPv4 address of the Freenet6 server is : 206.123.31.102 ---- - -With this information, a tunnel can be set up: - -SETTING UP THE TUNNEL CONFIGURATION ------------------------------------ - -Now, set up the configuration as follows: - -1. Enable IPv6 and set tunnel as default gateway in /etc/sysconfig/network: - - echo "IPV6_DEFAULTDEV=sit1">> /etc/sysconfig/network - -2. Create /etc/sysconfig/network-scripts/ifcfg-sit1, with the following: - ---- -DEVICE=sit1 -BOOTPROTO=none -ONBOOT=yes -IPV6INIT=yes -IPV6TUNNELIPV4=206.123.31.102 -IPV6ADDR=3ffe:b00:c18:1fff:0:0:0:7f5/128 ---- - -NOTE: You must use _sit1_ (or sit2,...). sit0 cannot be used, this is a -special device. - -NOTE: Some tunnel endpoints might require a different kind of prefix length; -for example, Cisco's usually favour /126. Using /0 creates a default route -through that interface. - -NOTE: If you're not directly connected to the Internet, you may want to use -ONBOOT=no instead. - -TUNNELING ---------- - -Tunnel can be brought up and down with: - - ifup sit1 - ifdown sit1 - -NOTE: In initscripts < 6.02 (ie. IPV6_TUNNELMODE=NBMA), even though sit1 is used, -'ip' sees the tunnel as sit0. This is due to an "interesting" implementation -of tunneling -- else multiple tunnels couldn't be used extensibly. - -NOTE: iproute tools give more reliable data, try e.g. '/sbin/ip addr ls'. - -MORE INFORMATION ----------------- - -http://www.bieringer.de/linux/IPv6/IPv6-HOWTO/IPv6-HOWTO.html is a good -source of IPv6 related Linux-information. -- cgit v1.2.1
