5.5.9.2 Confirmation of communication

Execute ping and ping ipv6 commands from the router and connection destination

router to the local and remote addresses set using tunnel information and confirm

the arrival performance. If no arrival performance is obtained, take the measures

below.

When no connectivity is found from either router

The route information is considered to have a problem, see Subsection 7.8.1,

“Communication cannot be done or communication is disconnected”.

When no connectivity is found from one of the routers

Confirm with the network configuration as to whether an address-converting

router is used between the relaying routes. If an address-converting router is

used, it falls under the prohibition configuration. Therefore, change the network

configuration so that no address-converting router is installed between the

relaying routes for setting the tunnels, see the GR2000 Applications Guide.

5.5.9.3 Confirmation of arrival route

Confirm the arrival route of the connection address set in the tunnel interface by

executing the show netstat routing-table numeric command. If the destination of the

route to be relayed is of another tunnel interface of this router, it may be conceivable

that it has become a multiplex tunnel of a prohibited configuration. Change the

setting of the route control so that an interface other than the tunnel interface will be

the relay destination.

5.5.10 Confirming the NAT-PT function

5.5.10.1 Confirmation during operation

(a) Confirmation of statistical information

The statistical information on NAT-PT is displayed when a show ipv6 natpt

statistics command is executed. The number of translated packets increases

when the translation using NAT-PT succeeds. If the translation using NAT-PT

fails, the number of packets that were not translated or discarded increases or no

counter increases. In a failure in translation, the setting of NAT-PT or the packets

are judged to be defective. See Subsection 7.8.4, “Troubleshooting NAT-PT

Communication Failures”, for how to locate the problem.
