Thanx 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.....!
