[j-nsp] New to Juniper: loopback interface address for the re0 configuration group?

[Raphael Maunier]

Here the config for the 2 re
groups {
    re0 {
        system {
            host-name re0.mx1.fqdn;
        }
        interfaces {
            fxp0 {
                unit 0 {
                    family inet {
                        address 10.10.10.9/24 {
                            master-only;
                        }
                        address 10.10.10.10/24;
                    }
                }
            }
        }
    }
    re1 {
        system {
            host-name re1.mx2.fqdn;
        }
        interfaces {
            fxp0 {
                unit 0 {
                    family inet {
                        address 10.10.10.9/24 {
                            master-only;
                        }
                        address 10.10.10.11/24;
                    }
                }
            }
        }
    }

    
And then apply-group [re0 re1]
