Displaying OSPF V3 Information

This display shows the following information.

For example, to display detailed information about all LSAs in the database, enter the show ipv6

ospf database extensive command at any CLI level.

TABLE 44 OSPF V3 database summary fields

Field Description

Area ID The OSPF area in which the Brocade 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 the LSA, in hexadecimal, from which the device learned this route.

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 Brocade 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 Brocade device uses the checksum to verify that the packet is not

corrupted.

Len The length, in bytes, of the LSA.
