Administrator Guide

• Did you congure 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, conguration, 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 conguration 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] 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.
Conguration Task List for OSPFv3 (OSPF for IPv6)
This section describes the conguration tasks for Open Shortest Path First version 3 (OSPF for IPv6) on the switch.
The conguration options of OSPFv3 are the same as those options for OSPFv2, but you may congure OSPFv3 with dierently labeled
commands. Specify process IDs and areas and include interfaces and addresses in the process. Dene areas as stub or totally stubby.
The interfaces must be in IPv6 Layer-3 mode (assigned an IPv6 IP address) and enabled so that they can send and receive trac. The
OSPF process must know about these interfaces. To make the OSPF process aware of these interfaces, assign them to OSPF areas.
The OSPFv3 ipv6 ospf area command enables OSPFv3 on the interface and places the interface in an area. With OSPFv2, two
commands are required to accomplish the same tasks — the
router ospf command to create the OSPF process, then the network
area command to enable OSPF on an interface.
