You could use bridge-domains within a Logical-Router to create a layer 2
segment capable of connecting multiple logical-routers:

logical-systems {
    r1 {
        interfaces {
            ge-0/0/4 {
                unit 0;
            }
            ge-0/0/5 {
                unit 0;
            }
            irb {
                unit 0 {
                    family inet {
                        address 10.0.5.254/24;
                    }
                }
            }
        bridge-domains {
            r1_domain {
                domain-type bridge;
                vlan-id none;
                interface ge-0/0/4.0;
                interface ge-0/0/5.0;
                routing-interface irb.0;
            }
        }
    }
    r2 {
        interfaces {
            ge-0/0/6 {
                unit 0 {
                    family inet {
                        address 10.0.5.1/24;
                    }
                }
            }
        }
    }
    r3 {
        interfaces {
            ge-0/0/7 {
                unit 0 {
                    family inet {
                        address 10.0.5.2/24;
                    }
                }
            }
        }
    }
}
