we are struggeling with a setup, where we have a BGP setup with our carrier and IPv4 works just fine (two endpoints on our side, two on theirs) on the same two connections we are also trying to advertise IPv6 prefixes, however, in that case the carrier router
spits out this error message. The FRR is running on a pfsense on our side, however, there is no need to use the ui to do the configuration, we did that already on the CLI.</div>
