Forcing shortest-path calculation updates

Manually initiate an SPF run, or calculation, to immediately update the OSPF LSDB. This configuration is useful if

  • you need to immediately restore a deleted OSPF-learned route

  • the routing table entries and the LSDBs do not synchronize

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.

About this task

This process is computationally intensive. Use this command only if required.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Double-click OSPF.
  3. Click the General tab.
  4. In the OspfAction area, select the runSpf option button.
  5. Click Apply.
  6. Click Yes to force an SPF run.

    After you initiate an SPF run, wait at least 10 seconds before you initiate another SPF run.
