Fahad, If you are looking for End-to-End failure detection for L2VPN where PE-CE links are Ethernet then You can do it either with BFD or IP SLA Cisco feature. Please be aware than BFD/IP SLA do not actually bring down the interface/subinterface, they either tear down IGP adjacencies (BFD), remove static routes (BFD/IP SLA) or disable PBR (IP SLA). HTH Cheers Alex

FREEK works....but there comes another issue like that....as we transport VLAN-TCC and VLAN-CCC clients. If there lastmile goes down.....VLAN BPDUs will still recieve over Turnk port (Switch to Juniper). So it coz L2Circuit to remain up. I look for the Ethernet/VLAN OAM that defines in 802.3ah. but its implementation is not possible on all layer 2 Switches. Also work on these standards are still in process. can u ppl tell me, Is there any other thing that can help me to detect the end to end failure for Layer 2 VPNs (CCC or TCC) like FREEK do for FR. Im looking for OAM or BFD....features.....does they can solve the issue.....!
