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] 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.
Configuration Task List for OSPFv3 (OSPF for IPv6)
This section describes the configuration tasks for Open Shortest Path First version 3 (OSPF for IPv6) on the switch.
The configuration options of OSPFv3 are the same as those options for OSPFv2, but you may configure OSPFv3 with differently labeled
commands. Specify process IDs and areas and include interfaces and addresses in the process. Define 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 traffic. 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.
NOTE
: The OSPFv2 network area command enables OSPF on multiple interfaces with the single command. Use the OSPFv3
ipv6 ospf area command on each interface that runs OSPFv3.
All IPv6 addresses on an interface are included in the OSPFv3 process that is created on the interface.
Enable OSPFv3 for IPv6 by specifying an OSPF process ID and an area in INTERFACE mode. If you have not created an OSPFv3 process,
it is created automatically. All IPv6 addresses configured on the interface are included in the specified OSPF process.
NOTE
: IPv6 and OSPFv3 do not support Multi-Process OSPF. You can only enable a single OSPFv3 process. To create multiple
OSPF processes you need to have multiple VRFs on a switch.
Set the time interval between when the switch receives a topology change and starts a shortest path first (SPF) calculation.
