METHOD AND APPARATUS FOR PROTOCOL DATA UNIT RECOVERY IN AN IS-IS SYSTEM

摘要

A method and apparatus for effectuating LSP recovery in an IS-IS router. When a standby router processor (RP) module of the IS-IS router is activated, at least one CSNP packet is generated by the newly activated RP module based on its link state database. The CSNP packet is then transmitted on all point-to-point links and all broadcast links supported by the IS-IS router.
