I wonder if you'd do this, if you could do L3 to the edge.

When you say redundant, do you mean that label can take any path between access port and termination IRB/BVI? Or do you actually have termination redundancy? If you don't have termination redundancy, you have two SPOF, access port and termination. If you do have termination redundancy, you're spending control-plane resource from two devices, doubling your control-plane scale/cost. I'm not saying it's bad solution, I know lot of people do it. But I think people only do it, because L3 at port isn't offered by vendors at lower rates. -- ++ytti
