Hi, We're trying to implement VPLS PE Redundancy with Supervisor Engine 2T (VSS) as described in http://www.cisco.com/en/US/prod/collateral/switches/ps5718/ps708/white_paper... and constantly failing. It seems so simple: set up a VSS, use LACP or PAgP port-channels to the distribution switches and do VPLS on the VSS. It just doesn't seem to work. Using WS-X6908-10G-2TXL line cards already gives less problems than with WS-X6704-10GE line cards, but still it fails to work very often. I sometimes wonder if I am going mad or if this setup has never actually been tested... So: has anybody ever set up a network like this, or am I really beta testing for Cisco now? Cheers, Sander Steffann

With a lot of thanks, credits etc to Arie Vayner: enabling 'mpls ldp graceful-restart' is a work-around for this problem. If you run into this situation look at: - https://supportforums.cisco.com/thread/2131580 - CSCsw70062 Cheers, Sander
