Configuring the Overload Bit for an IS-IS Device

Configuring the Overload Bit for an IS-IS Device

Pre-configuration Tasks

Before configuring the overload bit for an IS-IS device, configure basic IPv6 IS-IS functions.


  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS view is displayed.

  3. Run set-overload [ on-startup [ timeout1 | start-from-nbr system-id [ timeout1 [ timeout2 ] ] | wait-for-bgp [ timeout1 ] ] [ send-sa-bit [ timeout3 ] ] ][ allow { interlevel | external }* ]

    The overload bit for non-pseudonode LSPs is configured.

Verifying the Configuration

  • Run the display isis lsdb [ [ level-1 | level-2 ] | verbose | [ local | lsp-id | is-name symbolic-name ] ] * [ process-id | vpn-instance vpn-instance-name ] command to check information in the IS-IS LSDB.
