Suggestion for Layer 3, all SFP+ switches

I've been testing IPInfusion OcNOS running on Dell Z9100 and S4048.  I've
run a couple of test cases using MPLS LDP signaled port based and VLAN
based VPWS (pseudowire / e-line / xconnect / Juniper CCC) and VPLS (e-lan)
over an OSPFv2 IGP.  It's working well between Dell/IPI to Dell/IPI boxes.
We have had issues with the VPLS between Dell/IPI to Juniper/JunOS where
the circuit will show up on the Juniper and down on the Dell.  If we clear
LDP session on the Dell, it comes back up right away.  This seems to be
similar to what Aaron is seeing in his multi-vendor environment.  The price
on the Dell hardware is really good.  The features included with OcNOS are
much better than FTOS9.  If you aren't partial to Dell, you can run OcNOS
on a variety of other whitebox switches, like EdgeCore.

I haven't tested MP-BGP and L3VPN or BFD yet, but that is supposedly
supported in OcNOS as well.
