MPLS OAM Auto Protocol

MPLS OAM Auto Protocol

MPLS OAM, defined in ITU-T Recommendation Y.1710 and Y.1711, has the following drawbacks:

  • On an LSP, if OAM is enabled on the ingress later than it is enabled on the egress, or OAM is enabled on the egress and disabled on the ingress, a dLOCV fault occurs.

  • The dLOCV fault also occurs when OAM is disabled. You must disable OAM on the ingress and egress before changing the type or updating the interval for sending detection packets.

  • The OAM parameters need to be set on both the ingress and egress. This may cause the detection packet type and the interval for sending detection packets on the ingress to be different from those on the egress.

On Huawei devices, the OAM auto protocol can address the preceding problems.

The OAM auto protocol provides the following functions when enabled on the egress:

  • The first packet triggers OAM.
  • OAM can be enabled or disabled dynamically.

The MPLS OAM auto protocol is patented by Huawei.
