OSPF6 Debugging Information

The following debugging commands are available in config-ospf6 mode. Messages will be logged in accordance with the settings in Logging.

debug abr:

Enables debugging for Area Border Routers.

debug asbr:

Enables debugging for Autonomous System Boundary Routers.

debug flooding:

Enables debugging for Link State Advertisement flooding.

debug interface:

Enables debugging for OSPF6 interfaces.

debug border-routers (area <area-id>|router <router-id>):

Enables debugging for specific border routers, either by area or router ID.

debug lsa <lsa-type> <event-type>:

Enables LSA message debugging.

LSA Type:

Specifies a type of LSA message to debug, which must be one of the following: as-external, inter-prefix, inter-router, intra- prefix, link, network, router, unknown. These message types are described further in Link State Advertisement Message Types.

Event Type:

Specifies when to log debug information for the specified type of LSA message.

examine:

Enables debugging when examining LSA messages.

flooding:

Enables debugging when flooding LSA messages.

originate:

Enables debugging when originating LSA messages.

debug message (dd|hello|ls-acknowledgment|ls-request|ls-update|unknown) (recv|send):

Enables packet-level debugging of OSPF6 messages.

dd:

Debug database description packets.

hello:

Debug OSPF6 hello packets.

ls-acknowledgment:

Debug LSA acknowledgment packets.

ls-request:

Debug LSA request packets.

ls-update:

Debug LSA update packets.

unknown:

Debug OSPF6 messages of unknown types.

Message debugging entries are limited to a single direction:

send:

Debug messages sent by this router.

recv:

Debug messages received by this router.

debug neighbor event:

Enable debugging information for OSPF6 neighbor events.

debug neighbor state:

Enable debugging information for OSPF6 neighbor state changes.

debug route [(inter-area|intra-area|table)]:

Enables debugging for OSPF6 route calculations.

debug route memory:

Enables debugging for OSPF6 route table memory usage.

debug spf (database|process|time):

Debug SPF calculations

database:

Enable debugging for LSA message counts during SPF calculation

process:

Enable detailed debugging of the SPF calculation process.

time:

Enable debugging for SPF calculation timing.

debug zebra [(recv|send)]:

Enables OSPF6-specific debugging for dynamic routing manager daemon messages, in the send or receive direction, or both when the direction is omitted.
