Layer 3 Unidirectional Link Detection protocol (UDLD) support has been enabled.

The UDLD protocol enables to monitor the physical links and detect when a unidirectional link exists. Upon detection user can either block the port or notify the link status based on the network administration configuration.

UDLD works in two different modes:

For more information, see the Unidirectional Link Detection Configuration section in the OcNOS Layer 3 Configuration guide, Release 6.4.1.

When a multihomed CE is configured as an attachment circuit, the Ethernet Segment Route is sent. The main purpose of this route is to discover other PEs that share the ES and to perform DF elections, fast convergence, and Split Horizon.

Another route sent by PE, when a CE is multi-homed, is the Ethernet A-D Route per EVI. This is used to announce a label (unicast/alias label) that can be used for load sharing by the remote PEs.

Y1731 extensions of CFM (Connectivity Fault Management) like LM (Loss Measurement), DM (Delay Measurement), and SLM (Synthetic Loss Measurement) are supported on Single Homing scenario of EVPN-MPLS ELINE service.

The network administrator is generally informed about the failure in the connection based on the reception of CCM or by the user. The administrator then initiates Loop Back or Link Trace accordingly to quickly determine and then isolate the fault condition.

The CFM information is conveyed in Protocol frames called CFM PDUs. The CFM PDUs contain the appropriate control and status information used to detect, verify, and isolate faults. It also contains information for path discovery in CFM-enabled links.

Currently, this feature is supported only for EVPN-ELINE Single home and UP MEP services on both Qumran1 and Qumran2 series platforms.

For more information, refer to the section CFM Over VPWS in the OcNOS Carrier Ethernet, Release 6.4.1.

CFM provides capabilities useful for detecting, verifying and isolating connectivity failures in Virtual Bridged Local Area Networks through Continuity Check, Loop Back and Link Trace protocols. These capabilities are used in networks operated by multiple independent organizations, each with restricted access to each other's equipment.

The network administrator is generally informed about the failure in the connection based on the reception of Continuity Check Messages or by the user. The administrator then initiates Loop Back or Link Trace accordingly to quickly determine and then isolate the fault condition.

The CFM information is conveyed in Protocol frames called CFM Protocol Data Units (CFM PDUs). The CFM PDUs contain the appropriate control and status information used to detect, verify and isolate faults. It also contains information for path discovery in CFM-enabled links.

Currently, supported only for EVPN-ELINE Single home and up MEP service on both Qumran1 and Qumran2 series platforms.

For more information, refer to the section EVPN-ELINE Interface on Single Homing in the OcNOS Carrier Ethernet , Release 6.4.1.
