SRX340 route is Reject

I have rejected routes on a SRX340 and I don't understand why.  Also, the related irb interfaces have link down. That might be the problem but yet I don't know what those irb interfaces are down.  Does someone know why?

}
unit 71 {

        address 10.10.71.1/25;
    }
}

This firewall is linked to an EX4300 switch with a trunk

        vlan {
            members [ INNOV70 INBMGT ];
        }
    }
}

Would you need more information about my setup, let me know.

Thanks
