Configuring LSP Fragment Extension

Configuring LSP Fragment Extension

LSP fragment extension allows an IS-IS device to generate more LSP fragments to transmit more IS-IS information.

Pre-configuration Tasks

Before configuring LSP fragment extension, complete the following task:

NOTE:

When a new device connects to an IS-IS network, you are advertised to configure LSP fragment extension and virtual systems before establishing IS-IS neighbors or importing routes. If you establish IS-IS neighbors or import routes, which causes IS-IS to carry much information that cannot be loaded through 256 fragments, you must configure LSP fragment extension and virtual systems. The configurations, however, take effect only after you restart the IS-IS process.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run isis [ process-id ]

    The IS-IS view is displayed.

  3. Run lsp-fragments-extend [ [ level-1 | level-2 | level-1-2 ] | [ mode-1 | mode-2 ] ] *

    LSP fragment extension is enabled in an IS-IS process.

    By default, LSP fragment extension is disabled in an IS-IS process.

    If the mode or level is not specified during the configuration of LSP fragment extension, mode-1 and level-1-2 are used by default.

    NOTE:

    If there are devices of other manufacturers on the network, LSP fragment extension must be set to mode-1. Otherwise, devices of other manufacturers cannot identify LSPs.

  4. Run virtual-system virtual-system-id

    A virtual system is configured.

    By default, no virtual system is configured.

    To configure a router to generate extended LSP fragments, you must configure at least one virtual system. The ID of the virtual system must be unique in the domain.

    An IS-IS process can be configured with up to 50 virtual system IDs.

Verifying the Configuration

Run the following commands to check IS-IS process statistics.

  • display isis statistics [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] [ process-id | vpn-instance vpn-instance-name ]
  • display isis process-id statistics [ [ [ updated-lsp [ history ] ] [ level-1 | level-2 | level-1-2 ] ] | [ packet ] ]
