OcNOS SP : Multi-Protocol Label Switching Guide : Multi-Protocol Label Switching Configuration : Policing Configuration
Policing Configuration
This chapter contains a complete sample of configuration of Policing for Pipe and Uniform models.This example shows configurations using LDP.
Configuration
Configuring Remarking for MPLS EXP bits require following configurations:
• Enabling label-switching on the interface on NSM.
• Configuring LSP (Using LDP, Static or RSVP-TE, in this example we are using LDP for setting UP LSP).
• Running an IGP (Internal Gateway Protocol), for example, OSPF, to distribute reachability information within the MPLS cloud.
• Enable QoS, Configuring Policing on interface Level.
