[j-nsp] options for adding communities to an EVPN routing-instance?

[Michael Hare]

Adam-

I opened a JTAC case a few weeks back and was told to use the bgp export policy method.  I haven't tried it in our lab yet, as I'm not keen on the method.  To be fair I was looking at instance granularity, not mac address.  If I end up testing something, I'll report back.
