RFC 9489 defines the Label-Switched Path (LSP) Ping Mechanism for EVPN. This mechanism is widely used for Operations, Administration, and Maintenance (OAM) in MPLS networks. |

Our test focused on section 4.3.3, which specifically pertains to the EVPN-VPWS. We configured the EVPN VPWS between two DUTs. While the DUTs sent MPLS pings, we conducted a packet capture. We then verified the captured packets, confirming that the MPLS echo reply contained a return code set to 3, as specified by the RFC. |
