Hello Guillermo- I had a somewhat similar issue. For me I was trying to add a normal bgp community in vrf-export to an E-VPN instance. This config caused RPD core dumps in 18.2 although it worked as I had hoped in 16.1. JTAC reported at the time: "... using vrf-export in EVPN instance with non-rt target is not yet supported. Please don’t use it until it is officially targeted at 19.4 ... "
