Ok Henning.
I'm using 3.9, and my config is:
group "peering ASXXXX" {

        remote-as XXXX

        neighbor $principal {

                descr   "Link Principal"

                announce all

                local-address $mypeer1

                depend on carp1

                set metric 1

                set localpref 200

         }

        neighbor $backup {

                descr "Link BKP"

                announce all

                local-address $mypeer2

                depend on carp2

                set metric 10

                set localpref 100

         }

}
group "peering bogon" {

        remote-as 65333

        neighbor $peer_bogon1 {

                descr "Peering Bogon 1"

                local-address $my_bogon
