When configuring both IPv4 and IPv6 neighbours for a PVE node using the SDN/BGP Controller, only the IPv4 node is actually activated in the configuration.
Both IPs are added to the BGP peer group, but the peer group is only activated for the ipv4 address family. When running IPv6 only, everything works as expected.
