Arista 7280R (MPLS LSR)

Guys,

Has anyone got any experience running the Arista 7280R as an MPLS LSR, and if so, in a multivendor environment too (Cisco / Juniper)?

I'm currently looking at some short term options for a light replacement P core, and this and the QFX are looking like good options for 10GB/40GB (PE facing) and 10/100GB (Core facing) from a cost point of view. Not got a huge label stack (max of 3 label depth) and they will simply be switching labels.
