Modes

User EXEC mode

The show ipv6 ospf database command displays the following information:

Output field	Description
Area ID	The OSPF area in which the device resides.
Type	Type of LSA. LSA types can be the following: Rtr - Router LSAs (Type 1). Net - Network LSAs (Type 2). Inap - Inter-area prefix LSAs for ABRs (Type 3). Inar - Inter-area router LSAs for ASBRs (Type 4). Extn - AS external LSAs (Type 5). Link - Link LSAs (Type 8). Iap - Intra-area prefix LSAs (Type 9).
LS ID	The ID of LSA in Decimal.
Adv Rtr	The device that advertised the route.
Seq(Hex)	The sequence number of the LSA. The OSPF neighbor that sent the LSA stamps it with a sequence number to enable the device and other OSPF routers to determine which LSA for a given route is the most recent.
Age	The age of the LSA, in seconds.
Chksum	A checksum for the LSA packet. The checksum is based on all the fields in the packet except the age field. The device uses the checksum to verify that the packet is not corrupted.
Len	The length, in bytes, of the LSA.
Sync	Sync status with the slave management processor (MP).

The show ipv6 ospf database extensive command displays the following information:

Output field	Description
Router LSA (Type 1) (Rtr) Fields
Capability Bits	A bit that indicates the capability of the device. The bit can be set to one of the following: B - The device is an area border router. E - The device is an AS boundary router. V - The device is a virtual link endpoint. W - The device is a wildcard multicast receiver.
Options	A 24-bit field that enables IPv6 OSPF routers to support the optional capabilities. When set, the following bits indicate the following: V6 - The device should be included in IPv6 routing calculations. E - The device floods AS-external-LSAs as described in RFC 2740. MC - The device forwards multicast packets as described in RFC 1586. N - The device handles type 7 LSAs as described in RFC 1584. R - The originator is an active router. DC -The device handles demand circuits.
Type	The type of interface. Possible types can be the following: Point-to-point - A point-to-point connection to another router. Transit - A connection to a transit network. Virtual link - A connection to a virtual link.
Metric	The cost of using this router interface for outbound traffic.
Interface ID	The ID assigned to the router interface.
Neighbor Interface ID	The interface ID that the neighboring router has been advertising in hello packets sent on the attached link.
Neighbor Router ID	The router ID (IPv4 address) of the neighboring router that advertised the route. (By default, the router ID is the IPv4 address configured on the lowest numbered loopback interface. If the device does not have a loopback interface, the default router ID is the lowest numbered IPv4 address configured on the device.)
Network LSA (Type 2) (Net) Fields
Options	A 24-bit field that enables IPv6 OSPF routers to support the optional capabilities. When set, the following bits indicate the following: V6 - The device should be included in IPv6 routing calculations. E - The device floods AS-external-LSAs as described in RFC 2740. MC - The device forwards multicast packets as described in RFC 1586. N - The device handles type 7 LSAs as described in RFC 1584. R - The originator is an active router. DC -The device handles demand circuits.
Attached Router	The address of the neighboring router that advertised the route.
Inter-Area Prefix LSA (Type 3) (Inap) Fields
Metric	The cost of the route.
Prefix Options	An 8-bit field describing various capabilities associated with the prefix.
Prefix	The IPv6 prefix included in the LSA.
Inter-Area Router LSA (Type 4) (Inar) Fields
Options	A 24-bit field that enables IPv6 OSPF routers to support the optional capabilities. When set, the following bits indicate the following: V6 - The device should be included in IPv6 routing calculations. E - The device floods AS-external-LSAs as described in RFC 2740. MC - The device forwards multicast packets as described in RFC 1586. N - The device handles type 7 LSAs as described in RFC 1584. R - The originator is an active router. DC -The device handles demand circuits.
Metric	The cost of the route.
Destination Router ID	The ID of the router described in the LSA.
AS External LSA (Type 5) (Extn) Fields
Bits	The bit can be set to one of the following: E - If bit E is set, a Type 2 external metric. If bit E is zero, a Type 1 external metric. F - A forwarding address is included in the LSA. T - An external route tag is included in the LSA.
Metric	The cost of this route, which depends on bit E.
Prefix Options	An 8-bit field describing various capabilities associated with the prefix.
Referenced LS Type	If non-zero, an LSA with this LS type is associated with the LSA.
Prefix	The IPv6 prefix included in the LSA.
Link LSA (Type 8) (Link) Fields
Router Priority	The router priority of the interface attaching the originating router to the link.
Options	The set of options bits that the router would like set in the network LSA that will be originated for the link.
Link Local Address	The originating router’s link-local interface address on the link.
Number of Prefix	The number of IPv6 address prefixes contained in the LSA.
Prefix Options	An 8-bit field of capabilities that serve as input to various routing calculations: NU - The prefix is excluded from IPv6 unicast calculations. LA - The prefix is an IPv6 interface address of the advertising router. MC - The prefix is included in IPv6 multicast routing calculations. P - NSSA area prefixes are readvertised at the NSSA area border.
Prefix	The IPv6 prefix included in the LSA.
Intra-Area Prefix LSAs (Type 9) (Iap) Fields
Number of Prefix	The number of prefixes included in the LSA.
Referenced LS Type, Referenced LS ID	Identifies the router-LSA or network-LSA with which the IPv6 address prefixes are associated.
Referenced Advertising Router	The address of the neighboring router that advertised the route.
Prefix Options	An 8-bit field describing various capabilities associated with the prefix.
Metric	The cost of using the advertised prefix.
Prefix	The IPv6 prefix included in the LSA.
Number of Prefix	The number of prefixes included in the LSA.
