Troubleshooting OSPFv3
The system provides several tools to troubleshoot OSPFv3 operation on the switch. This section describes typical, OSPFv3
troubleshooting scenarios.
NOTE: The following troubleshooting section is meant to be a comprehensive list, but only to provide some examples of
typical troubleshooting checks.
● Have you enabled OSPF globally?
● Is the OSPF process active on the interface?
● Are the adjacencies established correctly?
●
Did you configure the interfaces for Layer 3 correctly?
● Is the router in the correct area type?
● Did you include the routes in the OSPF database?
● Did you include the OSPF routes in the routing table (not just the OSPF database)?
Some useful troubleshooting commands are:
● show ipv6 interfaces
● show ipv6 protocols
● debug ipv6 ospf events and/or packets
● show ipv6 neighbors
● show ipv6 routes
Viewing Summary Information
To get general route, configuration, links status, and debug information, use the following commands.
● View the summary information of the IPv6 routes.
EXEC Privilege mode
show ipv6 route [vrf vrf-name] summary
● View the summary information for the OSPFv3 database.
EXEC Privilege mode
show ipv6 ospf [vrf vrf-name] database
● View the configuration of OSPFv3 neighbors.
EXEC Privilege mode
show ipv6 ospf [vrf vrf-name] neighbor
● View debug messages for all OSPFv3 interfaces.
EXEC Privilege mode
debug ipv6 ospf [vrf vrf-name] [event | packet] {type slot/port[/subport]}
○ For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port/subport[/subport]
information.
○
For a 40-Gigabit Ethernet interface, enter the keyword fortyGigE then the slot/port information.
○ For a port channel interface, enter the keywords port-channel then a number.
○ For a VLAN interface, enter the keyword vlan then a number from 1 to 4094.
MIB Support for OSPFv3
SNMPv3 context name support implements MIB views on multiple OSPV3 instances.
