Description Use the lsp-fragments-extendcommand to enable LSP fragment extension in a specified mode and level.

Use the undo lsp-fragments-extendcommand to disable this feature.

The feature is disabled by default.

Note the following:

■After LSP fragment extension is enabled in an IS-IS process, the MTUs of all the interfaces on which this IS-IS process is enabled must not be less than 512; otherwise, LSP fragment extension will not take effect.

■At least one virtual system needs to be configured for the router to generate extended LSP fragments. An IS-IS process allows 50 virtual systems at most.

Examples # Enable LSP fragment extension of mode-1and Level-2.
