This chapter describes the Advanced Fault Propagation chapter, which covers Link Loss Forwarding (LLF), link state monitor and propagation by CFM, remote link state propagation, and restrictions for LLF, and includes tasks to configure LLF for CFM and for Layer 2 transport on the router.
Link Loss Forwarding
This topic describes Link Loss Forwarding (LLF), a mechanism used in networking to propagate the status of a network link to other connected devices.
Configure link loss forwarding for CFM
This topic describes how to configure LLF on a network by configuring a CFM domain and service, a MEP under the CFM domain and service, the continuity check message (CCM) interval on the MEP, Client Signal Fail (CSF) transmission and logging, and by enabling LLF on an interface.
Configure link loss forwarding for Layer 2 transport
This topic describes how to configure LLF for Layer 2 transport events by entering interface mode, configuring l2transport, and enabling LLF using the propagate remote-status command.
