Remote Defect Indication
Remote Defect Indication (RDI) is a single bit, is carried by CCM to convey the MEPs in MA about
reception of CCM messages by receiving MEPs (RMEP)
• The absence of RDI in a CCM indicates that the transmitting MEP is receiving CCMs from all
remote MEPs
• The presence of RDI indicates that transmitting MEP is not receiving CCM from one or more
RMEPs (one or more RMEP failed is in state) attached to the MEP.
• RDI is supported for all type of VLANs
• CVLAN, SVAN, ISID and BVLAN
• RDI is supported for regular and sub-second CCM intervals
Limitations
• UPMEP and MIP on C-VLAN ESI is not supported if it is a client of S-VLAN ESI (in Provider Edge).
• UPMEP and MIP on S-VLAN ESI is not supported if it is a client of ISID ESI (in Backbone Edge).
• Sub-second CCM interval is not supported for CES.
• RDI is not applicable for Link MA.
