Allow Exporting of Learned Routes in EVPN

[jasonmvp]

Certain manufactures like Arista have a way to re-advertise (re-export) already imported routes within a VRF using EVPN. For instance: if I import routes with RT 65000:200, I can turn around and re-export them from that same VRF with RT 65000:1000 or whatever. Arista does this with:

route-target export evpn imported-route

That only works on certain ASICs though. It's not universal.

Could FRR support this sort of feature? Would it be a costly update to the code? Or, better yet: is there a way to do it already, and I'm just not seeing the config options?

Thanks.

Thanks to Trey, I was reminded of the import vrf bit, and that does the trick.
