The set of routes (if any) that will be removed from the local LSP when the local LSP becomes full at either level. When set to 'external', all static routes and routes redistributed from other protocols will be removed from the local LSP (at all active levels) when the local LSP is full. If set to 'none', IS-IS will be unable to accept any additional configuration that may increase the size of the local LSP. The system administrator should modify the system configuration to reduce the local LSP size - for example, by reducing the number of addresses redistributed from other routing protocols, or by deleting circuit configuration. Once this has been done, if prvtIsisSysLspFullSuppress is set to 'external', the system is responsible for resynchronizing the set of routes with ISIS.
