There are also some warnings about use with GRES and NSR. They explain a
bit about GRES, but they don't say what's wrong with NSR. For IRR, it
seems that if the static database contains an "allow all" and the
ephemeral database contains the IRR filter, you should be good. Did you
get Juniper to confirm your use case is correct?
