3.10 IPv6 Unicast Routing Communication Failure

3.10.1

No RIPng Routing Information Exists

Isolate the problem according to the failure analysis method listed below if RIPng route information does not exist in
the displayed route information acquired by this system.
Table 3-35: Failure Analysis of RIPng
No. Troubleshooting Steps and Command
1 RIPng neighboring information is displayed.
show ipv6 rip neighbor
2 Check to see if the RIPng setting is correct in
configuration.
3 Confirm that the routing are not filtered by
referring to the configuration.
3.10.2

No OSPFv3 Routing Information Exists

Isolate the problem according to the failure analysis method listed below if OSPFv3 route information does not exist in
the displayed route information acquired by this system.
Table 3-36: Failure Analysis of OSPFv3
No. Troubleshooting Steps and Command
1 Check the interface status of OSPFv3.
show ipv6 ospf interface <Interface
Name>
2 Check the status of a neighboring router of DR
from Neighbor List.
3 Check the status of all neighboring routers from
Neighbor List.
4 Check to see if the OSPFv3 setting is correct in
configuration.
5 Check the OSPFv3 routes that have been
learned.
show ipv6 route all-routes
6 Confirm that the routing are not filtered by
referring to the configuration.

Troubleshooting Functional Failures in Operation
Go to No. 2 if the interface of a neighboring router is not displayed.
Go to No. 3 if the interface of a neighboring router is displayed.
Go to No. 3 if the configuration is correct.
Correct the configuration if it is not correct.
Check to see if the neighboring router advertises the RIPng route.
Correct the configuration if it is not correct.
Go to No. 3 if the interface status is DR.
Go to No. 2 if the interface status is BackupDR or DR Other.
Execute the command again after a certain period if the interface status is
"Waiting." Go to No. 1.
Go to No. 4 if the status of the neighboring router of DR is other than Full.
Go to No. 5 if the status of the neighboring router of DR is Full.
Go to No. 4 if the status of some neighboring routers is other than Full.
Go to No. 5 if the status of all neighboring routers is Full.
Go to No. 5 if the configuration is correct.
Correct the configuration if it is not correct.
Go to No. 6 if the route is set to "InActive."
If no route exists, check to see if the neighboring router advertises the
OSPFv3 route.
Check to see if the neighboring router advertises the OSPFv3 route.
Correct the configuration if it is not correct.
