Summary

In this chapter, you have seen what the purpose of the Label Distribution Protocol (LDP) is. This chapter included an in-depth look at the four main functions of LDP:

  • The discovery of LSRs that are running LDP

  • Session establishment and maintenance

  • Advertising of label mappings

  • Housekeeping by means of notification

Some LDP-specific features were covered. You learned about the controlling of label advertisements with LDP, the inbound filtering of label bindings, LDP Autoconfiguration, MPLS LDP-IGP Synchronization, and LDP Session Protection. The functions of LDP and the LDP features were illustrated with configuration examples and the commands to troubleshoot and verify the correct operation of LDP.
