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_pap=
er_c11-663645.html#wp9000139 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?
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:
