MPLS OAM

MPLS OAM provides tools for fault detection, performance monitoring, and path verification in MPLS networks through LSP ping and traceroute capabilities. This feature enables Data Plane Monitoring (DPM) for proactive fault detection, echo protocol configuration for LSP verification, and BFD integration for fast failure detection across MPLS Label Switched Paths.

Example YAML Code:

Example-1: EMPLS OAM with DPM (Data Plane Monitoring).

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        mpls_oam:
          enable: true
          dpm:
            pps: 10
            interval: 60

Example-2: MPLS OAM with echo reply and vendor extension settings.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        mpls_oam:
          enable: true
          echo:
            disable_vendor_extension: true
            reply_mode_control_channel_allow_reverse_lsp: true

Example-3: MPLS OAM with echo revision settings.

iosxr:
  devices:
    - name: router-1
      host: 10.10.10.1:57400
      configuration:
        mpls_oam:
          enable: true
          echo:
            revision: 4
