Configuring other network devices

The other devices on the internal network all support IPv6, and are running RIPng where applicable. They only need to know the internal interface network addresses of the FortiGate units.

The ISP routers need to know the FortiGate unit information such as IPv6 addresses.

Testing the configuration

In addition to normal testing of your network configuration, you must also test the IPv6 part of this example. For troubleshooting problems with your network, see the FortiOS Handbook Troubleshooting chapter.

For troubleshooting problems with RIP, see RIPng — RIP and IPv6 on page 331.

Testing the IPv6 RIPng information

There are some commands to use when checking that your RIPng information is correct on your network. These are useful to check on your RIPng FortiGate units on your network. Comparing the output between devices will help you understand your network better, and also track down any problems.

diagnose ipv6 address list

View the local scope IPv6 addresses used as next-hops by RIPng on the FortiGate unit.

diagnose ipv6 route list

View ipv6 addresses that are installed in the routing table.

get router info6 routing-table

View the routing table. This information is almost the same as the previous command (diagnose ipv6 route list) however it is presented in an easier to read format.

get router info6 rip interface external

View brief output on the RIP information for the interface listed. The information includes if the interface is up or down, what routing protocol is being used, and whether passive interface or split horizon are enabled.

get router info6 neighbor-cache list

View the IPv6/MAC address mapping. This also displays the interface index and name associated with the address.
