Viewing the link-state database

View the area advertisements and other information in the LSDB to ensure correct OSPF operations.

Before you begin

  • Change the VRF instance as required to configure OSPF on a specific VRF instance. The VRF must have an RP trigger of OSPF. Not all parameters are configurable on non-default VRFs.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Click OSPF.
  3. Click the Link State Database tab.

Link State Database field descriptions

Use the data in the following table to use the Link State Database tab.

Name

Description

AreaId

Identifies the area. The OSPF backbone uses the area ID 0.0.0.0.

Type

Specifies the OSPF interface type. Broadcast LANs, such as Ethernet and IEEE 802.5, use broadcast; X.25 and similar technologies use NBMA; and links that are point-to-point use pointToPoint.

Lsid

Identifies the piece of the routing domain that the advertisement describes.

RouterId

Identifies the router in the autonomous system.

Sequence

Identifies old and duplicate link-state advertisements.

Age

Specifies the age, in seconds, of the link-state advertisement.

Checksum

Contains the checksum of the complete contents of the advertisement, except for the age parameter. The checksum does not include the age parameter so that advertisement age increments without updating the checksum.
