I do not really have much experience with EX-series and layer 3. I let
the MX80s do the VRRP and OSPF, which has not been entirely smooth
sailing lately.

No, the EX4200 would have to handle a dual tag push, and the hardware
can't do that. Rumour has it that the EX4500 and EX4550 has the
necessary hardware, but even if that turns out to be true, their
software can't do it (yet?).
