Hi, The interop stuff was a resounding success, and the details are at http://pieknywidok.blogspot.co.nz/2013/06/brocade-and-juniper-interop-ospf-m... if anyone is interested. I'm now trying to engineer it so we can add Juniper devices while changing as little Brocade config as possible. Can anyone help me with the following questions: - How many LSPs can a Brocade MLX4/MLX8 handle before it falls over? We have a mesh of 15 chassis, and the output of "show mpls memory" looks like this: Mem-Type Alloc BytesAlloc TotalAlloc TotalFree AllocPeak AllocFail FreeFail LSP 28 25760 369 341 28 0 0 Does this mean that it's full? The documentation is sparse, I'm hoping someone else has gone down that rabbit hole and found an answer for me :) - What MTU are people using for VLL/VPLS? - Has anyone got QinQ working with VLL/VPLS on a Brocade? - Does anyone have a preference for raw mode vs tagged mode for VLL and VPLS? Cheers Sam
