Dear Nagendra,
Thanks your reply ! I used this devices to configure VPLS ( 3750--7609 -----ASR 1004 --2950 ), but the VC status is down .I referenced the official configuration and asked my friends ,still couldn't find the reasons. It's the issue of devices compatibility ?
If you have time ,can you help me Analysis the problem ?
Thank you very much !
