RIP and IPv6
RIP Next Generation (RIPng) is a new version of RIP was released that includes support for IPv6.
The FortiGate unit command config router ripng is almost the same as config router rip, except that IPv6 addresses are used. Also if you are going to use prefix or access lists with RIPng, you must use the config router access-list6 or config prefix-list6 versions of those commands.
If you want to troubleshoot RIPng, it is the same as with RIP but specify the different protocol, and use IPv6 addresses. This applies to commands such as get router info6 when you want to see the routing table, or other related information.
If you want to route IPv4 traffic over an IPv6 network, you can use the command config system ip6-tunnel to configure the FortiGate unit to do this. The IPv6 interface is configured under config system interface. All subnets between the source and destination addresses must support IPv6. This command is not supported in Transparent mode.
For example, you want to set up a tunnel on the port1 interface starting at 2002:C0A8:3201:: on your local network and tunnel it to address 2002:A0A:A01:: where it will need access to an IPv4 network again. Use the following command:
config system ipv6-tunnel
edit test_tunnel
set destination 2002:A0A:A01::
set interface port1
set source 2002:C0A8:3201::
end
end
The CLI commands associated with RIPng include:
config router ripng
config router access-list6
config router prefix-list6
config system ipv6-tunnel
get router info6 *
